Ultrasonic frequency signals can be employed in a manner similar to radio frequency signals for target detection and ranging by utilizing concepts from radar systems. This project uses components operating in the ultrasonic frequency spectrum to transmit and receive signals for detection and ranging. The project concept contains a single channel ultrasonic transmitter and a single channel ultrasonic receiver. An Arduino Due microcontroller is used to coordinate the radar system. The radar transmitter is continuously transmitting chirp waveforms in a frequency sweep pattern from 30 kHz to 50 kHz. Chirp echoes are received by the ultrasonic microphone. The echoes are mixed with the originally transmitted chirp, which creates a beat frequency response. The beat frequency is used to calculate the range of the target.
