Wireless ranging node and wireless ranging method

The invention discloses a wireless ranging node and a wireless ranging method. The wireless ranging node comprises a central processing unit, a Chirp signal radio frequency unit, a radio frequency front end unit, a power supply unit, a sensor unit and a data communication unit. The Chirp signal radio frequency unit is used for mutual conversion between digital signals and radio-frequency signals, the radio frequency front end unit is used for amplifying and filtering Chirp signals, the power supply unit is used for supplying a working power supply, and the sensor unit is used for providing node information. According to the wireless ranging node, the sensor unit informs the central processing unit of a motion state of the whole node, and the central processing unit controls the whole node to enter a working state with low power consumption at a proper moment. The wireless ranging method improves ranging accuracy of SDS-TWR through the characteristic that an actual time interval for continuously sending data t
