Wireless ranging method based on CSS (chirp spread spectrum sequence) technology and CSS wireless terminal

The invention discloses a wireless ranging method based on the CSS (chirp spread spectrum sequence) technology and a CSS wireless terminal. According to the design, on the basis of the CSS technology, the chirp spread spectrum sequence with the strong anti-jamming capability is adopted, the transmitter and receiver end is based on the symmetrical-face two-way ranging algorithm, the digital matched filter design technology is adopted in a matched manner, and the ranging accuracy can be improved by being smaller than 1 meter.
