Radar is an instrument that uses microwaves to detect distant objects by measuring the echo of pulses. During World War II, countries rushed to develop radar systems for military use. Britain was a leader in radar development before the war and built radar stations around the country to detect incoming aircraft. There were two main types of radar used in WWII - detection radars to map surrounding areas and detect objects, and fire control radars to precisely locate targets to allow guns to hit targets that couldn't be seen directly. Early radar displays were like electronics lab equipment, but the PPI display, showing a rotating beam and target locations, became more useful for operators. Radar has since been developed for navigation and now has applications beyond military and weather

Mechanical Aspects in Stealth Technology
Stealth refers to the act of trying to hide or evade detection.
Stealth technology is ever increasingly becoming a paramount
tool in battle especially “high technology wars” if one may
occur in the future where invincibility means invincibility.
Able to strike with impunity, stealth aircraft, missiles and
warships are virtually invisible to most types of military
sensors. The experience gained at the warfront emphasizes the
need to incorporate stealth features at the design stage itself.
The other purpose is to share the recent achievements related to
the advanced composite materials used on various aerostructures
across the globe. Also discussed are the possibilities
of achieving stealth capability on our existing fleet of fighter
and bomber aircrafts of our Indian Armed forces using
composite and smart materials.
Stealth technology also known as LOT (Low Observability
Technology) is a technology which covers a range of
techniques used with aircraft, ships and missiles, in order to
make them less visible (ideally invisible) to radar, infrared and
other detection methods.
Stealth Technology essentially deals with designs and materials
engineered for the military purpose of avoiding detection by
radar or any other electronic system.
Stealth aircraft are aircraft that use stealth technology to make
it harder to be detected by radar and other means than
conventional aircraft by employing a combination of features
to reduce visibility in the visual, audio, infrared and radio
frequency (RF) spectrum. Well known examples include the
United States' F-117 Nighthawk (1980s-2008), the B-2 Spirit
"Stealth Bomber," and the F-22 Raptor.

The concept originated in the 1950s but Amazon launched the first major public cloud in 2006. Cloud computing has three main components - clients that access the cloud, distributed servers that host applications and data, and data centers that house these servers. There are different types of clients, deployment models for clouds, service models, and cloud computing enables scalability, reliability, and efficiency for applications accessed over the Internet like email, social media, and search engines.
stealth technology (paper presentation )
Stealth technology uses techniques to make personnel, aircraft, ships, missiles, and satellites less visible to detection methods like radars, infrared, sonar. It began with experiments in World War I to make military aircraft less visible. During World War II, radars were developed for detecting aircraft, creating a need for stealth. Stealth works by having flat surfaces and sharp edges that reflect radar signals away at different angles. Surfaces can also absorb radar energy. The overall effect is that stealth aircraft like the F-117A have a very small radar cross-section, similar to a small bird. Counter radars were then developed that use different tracking techniques to detect stealth vehicles. Current research continues to advance stealth capabilities.

It then defines stealth as using techniques to make vehicles less visible to radar, infrared, sonar and other detection methods. The key is minimizing signatures and signals to prevent detection. For air vehicles, radar and infrared signatures are most important to reduce. The document discusses the basic principles of stealth technology and how it aims to reduce radar cross-section and other signatures. It provides a brief history of stealth's development and defines the different types of signatures stealth techniques aim to minimize.
Mechanical Aspects in Stealth Technology
Stealth refers to the act of trying to hide or evade detection. Stealth technology is ever increasingly becoming a paramount tool in battle especially “high technology wars” if one may occur in the future where invincibility means invincibility. Able to strike with impunity, stealth aircraft, missiles and warships are virtually invisible to most types of military sensors. The experience gained at the warfront emphasizes the need to incorporate stealth features at the design stage itself. The other purpose is to share the recent achievements related to the advanced composite materials used on various aero structures across the globe. Also discussed are the possibilities of achieving stealth capability on our existing fleet of fighter and bomber aircrafts of our Indian Armed forces using composite and smart materials. Stealth technology also known as LOT (Low Observability Technology) is a technology which covers a range of techniques used with aircraft, ships and missiles, in order to make them less visible (ideally invisible) to radar, infrared and other detection methods.
Stealth Technology essentially deals with designs and materials engineered for the military purpose of avoiding detection by radar or any other electronic system. Stealth aircraft are aircraft that use stealth technology to make it harder to be detected by radar and other means than conventional aircraft by employing a combination of features to reduce visibility in the visual, audio, infrared and radio frequency (RF) spectrum. Well known examples include the United States' F-117 Nighthawk (1980-2008), the B-2 Spirit "Stealth Bomber," and the F-22 Raptor.
Mechanical Aspects in Stealth Technology
Stealth technology aims to make objects invisible to radar detection. It involves shaping vehicles to deflect radar signals and coating them with radar-absorbing materials. Key stealth aircraft include the F-117 Nighthawk, B-2 Spirit, F-22 Raptor, and F-35 Lightning II. India is developing stealth capabilities through programs like the HAL Light Combat Helicopter, Sukhoi T-50, DRDO AURA unmanned bomber, and the future HAL AMCA stealth fighter. Further advances may involve hypersonic flight, infrared cloaking, and plasma stealth technologies.
Radar bullet
The document discusses radar bullets, which are special bullets used to detect landmines. Radar bullets are fired into the ground and emit powerful radio waves in a 15 meter radius to detect any landmines. The radio waves reflect off landmines and their images are received by an antenna on a helicopter. Radar bullets have advantages of low power consumption and a small, simple structure. However, they cannot indicate the exact range of targets and distinguishing multiple targets can require complex circuitry. Radar bullets can be used to detect both buried landmines and illegal pipelines to aid in national security efforts.
Ubp electronics in defence
Strategic electronics has faced a paradigm shift due to private sector involvement in India's defense market, though most remains state-controlled. Unmanned aerial vehicles (UAVs) are increasingly used for military and civilian purposes like surveillance, weather monitoring, and law enforcement. Radar and sonar are key technologies for detecting objects at a distance using radio waves and sound, respectively. They are widely used for applications like air traffic control, submarine detection, and mapping the seafloor. India's defense industry includes major public sector undertakings focused on aeronautics, electronics, shipbuilding, and weapons development.
RADAR
Radar is a technology used widely by the defence systems all around the world. It was a technology developed during the World War 2.
Night Vision
Night vision technology was first developed during World War II to provide military advantages at night. Early devices used image intensification or infrared illumination to allow vision in dark conditions. Major developments included more effective micro-channel plates and thermal imaging capabilities. Later generations saw improvements in image quality and device lifespan. In the 1980s, night vision applications expanded from military to civilian uses such as hunting, surveillance, and security.
Guided Missiles2 2003
Guided missiles have evolved significantly over time and now play a major role in modern warfare. They can be guided through various technologies including laser, infrared, radar and GPS systems to precisely target enemies. Future smart weapons are anticipated to have greater autonomy, using advanced sensors and software to identify and engage threats on their own.

An unmanned aerial vehicle (UAV), or drone, is an aircraft without a human pilot that is controlled autonomously or remotely. The document discusses the history of UAV development from early attempts in 1916 to current military and research applications. It provides details on Indian UAVs developed by DRDO and HAL such as Rustom and Nishant, and compares specifications of the US Global Hawk drone to the Indian Rustom-H. The uses, advantages, and disadvantages of UAVs are outlined.
Drone-Unmanned Aerial Vehicle
An unmanned aerial vehicle (UAV), commonly known as a Drone, is an aircraft without a human pilot on board. UAVs can be remote controlled aircraft (e.g. flown by a pilot at a ground control station) or can fly autonomously based on pre-programmed flight plans or more complex dynamic automation systems
A UAV is defined as being capable of controlled, sustained level flight and powered by a jet or reciprocating engine. In addition, a cruise missile can be considered to be a UAV, but is treated separately on the basis that the vehicle is the weapon.
Unmanned Aerial Vehicles (UAVs) are aircrafts that fly without any humans being onboard. They are either remotely piloted, or piloted by an onboard computer. This kind of aircrafts can be used in different military missions such as surveillance, reconnaissance, battle damage assessment, communications relay, minesweeping, hazardous substances detection and radar jamming. However they can be used in other than military missions like detection of hazardous objects on train rails and investigation of infected areas. Aircrafts that are able of hovering and vertical flying can also be used for indoor missions like counter terrorist operations

Webinar: Designing a schema for a Data Warehouse
Are you new to data warehouses (DWH)? Do you need to check whether your data warehouse follows the best practices for a good design? In both cases, this webinar is for you.
A data warehouse is a central relational database that contains all measurements about a business or an organisation. This data comes from a variety of heterogeneous data sources, which includes databases of any type that back the applications used by the company, data files exported by some applications, or APIs provided by internal or external services.
But designing a data warehouse correctly is a hard task, which requires gathering information about the business processes that need to be analysed in the first place. These processes must be translated into so-called star schemas, which means, denormalised databases where each table represents a dimension or facts.
We will discuss these topics:
- How to gather information about a business;
- Understanding dictionaries and how to identify business entities;
- Dimensions and facts;
- Setting a table granularity;
- Types of facts;
- Types of dimensions;
- Snowflakes and how to avoid them;
- Expanding existing dimensions and facts.
