This document discusses embedded systems and radar. It defines an embedded system as a combination of computer hardware and software designed for a specific function. It then defines radar as using radio detection and ranging, describing how radar works and the types of radar. It lists the common hardware and software used in radar and describes some of its features, advantages, disadvantages, operational attributes, and how it compares to lidar.

3. What is an EMBEDDED
SYSTEM..??
An embedded system is some
combination of computer hardware and
software, either fixed in capability or
programmable, that is specifically
designed for a particular function.

R A = RAdio
d = detection
A = And
R = RAnging.

15. COMPARISION BETWEEN :
 LIDAR (Light Detection And Ranging)  RADAR(RAdio Detection And Ranging)
 LIDAR uses ultraviolet visible, or near  Radar is an object detection system which
infrared light to image objects and uses radio waves to determine the range,
can be used with a wide range of altitude, direction, or speed of objects.

 It helps to scan aircraft,ships, spacecraft,guided
 It helps to scan non-metallic objects, missiles,motor vehicles,weather formations,and
rocks, rain, chemical terrain.
