Dynamic Ranging Radar SensorDetailed Description：
WORKING PRINCIPLE：
The LD-02 series of millimeter wave dynamic ranging radar sensor uses the principle of FMCW (Frequency Modulated Continuous Wave) to transmit a continuous wave with a changing frequency during the frequency sweep period. The echo reflected by the object has a certain frequency difference with the transmitted signal. The frequency difference can obtain the distance information between the target and the radar.
