A Miniature Radar for Critical Mission Application

In this paper, we present a prototype of a miniature radar system using the ESP32 microcontroller and an HC-SR04 ultrasonic sensor. The prototype utilizes a servo motor to rotate the ultrasonic sensor across a 180-degree arc to mimic the functionality of traditional radar systems. The prototype enables the radar to scan and detect objects and support applications in autonomous vehicle navigation, monitoring, and proximity detection in smart home systems. The prototype highlights the adaptability of the ESP32 and ultrasonic technology in creating cost-effective, scalable, and efficient radar-like systems.
