The document outlines the development of a low-cost ultrasonic radar system using Arduino that detects objects up to 400 cm away and displays their position visually. The system integrates ultrasonic sensors, a microcontroller, and a graphical display for alarms, with a rotation range of 0 to 150 degrees. Experimental results indicate successful object detection, and potential future enhancements may increase range and capabilities.

1.  Radars have been used for airport air-traffic control,
highway patrol, ballistic missile guidance, military exercise and
many other applications.
 In this poster, we developed a low-cost tiny ultrasonic radar
system based on Arduino.
 It utilizes ultrasonic sensors to detect the object in the range
and passes the information to Arduino microcontroller .
 Once the object is detected, The graphical display utilizes the
position of the detected objects on the computer to send visual
alarm on LED screen.
 By adjusting the rotation of the servomotor, we allow the
sensing to be in range from 0 degree to 150 degrees.
 It can detect objects up to 400cm away from the ultrasonic
sensor.

2.  RADAR stands for Radio Detection and Ranging
System.
 RADAR is an object detection system which
uses radio waves to determine the range, altitude,
direction, or speed of objects
 It is basically an electromagnetic system used to
detect the location and distance of an object from
the point where the RADAR is placed.
 It works by radiating energy into space and
monitoring the echo or reflected signal from the
objects.
 It operates in the UHF and microwave range.

3.  In this Radar System we will be using an Ultrasonic
Sensor to determine the presence of any object in a
particular range.
 We will be using different hardware like Arduino
UNO, HC-SR04 Ultrasonic Sensor and a Servo Motor
but the main aspect is the visual representation in
the Processing Application.
 The Ultrasonic Sensor collects the information with
the help of Arduino and pass it to the Processing
where a simple Graphics application is implemented
to mimic a Radar Screen.

4. HARDWARE COMPONENTS:
 Arduino UNO
 HC-SR04 Ultrasonic Sensor
 TowerPro SG90 Servo Motor
 Connecting Wires
 Jumper Cables
 5V Power Supply
 USB Cable (for Arduino)
SOFTWARE USED:
 Arduino IDE
 Processing Application

6.  Ultrasonic sensors generate high frequency sound
waves and evaluate the echo which is received back by
the sensor.
 Sensors calculate the time interval between sending the
signal and receiving the echo to determine the distance
to an object.
 Systems typically use a transducer which generates
sound waves in the ultrasonic range, above 18,000
hertz, by turning electrical energy into sound.
 Then upon receiving the echo turn the sound waves
into electrical energy which can be measured and
displayed.

7. The modern uses of radar are highly diverse, including
 Air traffic Control,
 Radar Astronomy.
 Air-defense System.
 Antimissile System.
 Marine Radars to locate landmarks and other ships.
 Aircraft Anti-collision Systems.
 Ocean Surveillance Systems.
 Outer space Surveillance and Rendezvous Systems.
 Meteorological precipitation Monitoring.
 Altimetry and Fight control System.
 Guided Missile target locating Systems and
 Ground Penetrating Radar for geological observations.

8.  The Prototype of the System is implemented and
coding for Arduino control is developed.
 Experimental results show that the system can
detect objects within the range successfully.

9.  In this project using Arduino board the radar
system was implemented.
 It succeed in helping to be widely used to help
detect objects in different environments.
 In the future it can be updated to used for a
larger range and advancements.
