This is basic radar functionality, done with an Arduino Uno and a basic stepper moving a Ping sensor. At each step of the stepper the Ardunio uses the Ping sensor to measure the distance and sends that data down the serial channel with the angle the stepper is pointing. It moves fast enough to operate as a basic radar.
