Design and Implementation of Indoor Radar based on Ultrasonic

Ultrasonic waves are used instead of electromagnetic waves as detection means to design an indoor radar system. The problems of large radar close range blind area and radiation hazards are solved. It is used for radar principle demonstration verification. A sink ring is set inside the head to realize uninterrupted scanning of the antenna in the same direction. An ultrasonic transceiver device is used to transmit ultrasonic signals and also to receive the echo signals scattered by the target for target detection. The signal acquisition device is used to generate the trigger pulse signal, perform AD conversion on the echo signal, count the angle coded signal and give the antenna orientation information. The display control software is used for human-computer interaction. The results show that the system can simulate radar distance measurement, angle measurement and other functions with high measurement accuracy and good intuitiveness.
