A ranging and communication multifunction system processable by integrating a ranging function and a communication function is provided. The ranging and communication multifunction system 1 of the present invention includes a transmission unit 2 and a receiving unit 3, and integrates two functions of ranging and communication. The transmission unit 2 includes a transmission circuit 4, a carrier wave modulation device 5, and a transmission antenna 6, and the receiving unit 3 includes a receiving circuit 7, a wave detector 8, a low noise amplifier (LNA) 9, and a receiving antenna 10. The data modulation performed in the transmission circuit 4 uses a PPM system. The receiving circuit 7 provides a ranging circuit 11 and a communication circuit 12 separately, so that the demodulation processing of ranging and communication can be performed in parallel.
