[0002] Characteristics of radio frequency sensors: No direct contact with the target object is required, and moving objects or objects that are difficult to access can be detected, thus avoiding interference and damage to the measured object. It can provide high-precision measurement results, and the measurement resolution of parameters such as distance and speed can reach centimeter or even millimeter level. Radio frequency band is used for signal transmission and detection. The signal in this frequency band has strong anti-interference ability and can work stably in complex electromagnetic environments.

[0003] However, existing radio frequency sensors often detect the target area through a single radio frequency sensor. The detection effect of a single radio frequency sensor is too concentrated, which will lead to an increase in the blind area of ​​detection, thereby affecting the accuracy and reliability of the overall detection.
