A technology called radar uses waves to identify objects and determine their location, height, direction, or speed. Ultrasonic radar is the application of ultrasonic waves in place of electromagnetic waves [1], [2]. Similar to radar, ultrasonic sensors function by listening for wave echoes. Radar information can be shown via LEDs, LCD displays, or sound alerts. In this work, we used an ultrasonic sensor to create basic radar. It measures angles between 15 and 165 degrees and distances between 3 and 40 cm without touching [3]-[5]. A tiny motor drives the sensors and specialized software displays the data on a PC screen [6]-[8].This work aims to build a functional ultrasonic radar system that can keep an eye on a specific area. Since its inception, ultrasonic sensing technology has been used in a variety of applications, such as proximity detection in robots, home security systems, distance and tank level monitoring, and manufacturing lines. Numerous applications have made it feasible to fix technical issues more quickly and affordably without sacrificing stability, quality, or safety [9], [10].
