Radar is a very important tool in the military as it is used to detect aircrafts, vehicles and missiles. Sonar is a very common technique used in submarines and other underwater vessels. It uses sound propagation to detect objects in the water.
In this project, we have used ultrasonic sensor, servo motor connected to the microcontroller. The servo motor is used to rotate the radar system from 0 to 180 degree and the distance between the integrated system and the obstacle is calculated by the ultrasonic sensor.
The Processing IDE helps to draw a graph around the radar system and the obstacle detected by the sonar waves emitted from ultrasonic sensor is denoted by red marking.
