RADAR is a detection system that uses radio waves to determine the characteristics of the detected objects such as: range, height, direction, or the speed of objects. In this paper, we designed a radar system that uses an ultrasonic sensor to det ect objects. In this paper, the ultrasonic is used to measure the distance between the radar and any object -based non-contact technology. Whereas, the movement of the sensor is controlled by using a small servo motor. This radar -controlled using the Arduino Uno board as a microcontroller. The signal received from the sensor would be processed using “Processing Development Environment Software," then the result would be shown on a PC screen. by Sahar Alkassar
