ARDUINO BASED ULTRASONIC RADAR

Radio detection and ranging, that is, RADAR is a radio wave technique to determine the scope of the object, angle or speed. It is object detection technology. It is used to detect aircraft, ships, spacecraft, missiles, motor vehicles, weather formation and terrain. The proposed "Ultrasonic Radar System" uses an ultrasonic module that includes an ultrasonic transmitter and receiver as well as an AVR microcontroller ATmega328. It works by launching a short pulse at the ear audible frequency, after that microcontroller listens for echoes. The information about the distance to the object is given at the time elapsed during transmission to the echo reception. Here, the objective is to design an ultrasonic radar system by plotting its graph with the help of SOFTWARE to identify the location of the object and its angle in the unauthorized area.
