Abstract

The invention provides a TDOA-assisted RID signal receiving control method and device. The method comprises the following steps: acquiring a positioning signal; positioning the target unmanned aerial vehicle according to the positioning signal to obtain unmanned aerial vehicle position information at multiple moments; determining a predicted flight path of the target unmanned aerial vehicle according to the unmanned aerial vehicle position information at the multiple moments; selecting M RID receiving antennas from a plurality of RID receiving antennas according to the predicted flight path; according to the method, the receiving capability of the RID sending signals of the target unmanned aerial vehicle in the dynamic flight process is improved, the signal receiving requirements under urban and other complex terrain conditions are met, the receiving capability of the RID sending signals is high, the stability is high, the method is not influenced by the terrain and the dynamic flight of the target unmanned aerial vehicle, and the reliability of the target unmanned aerial vehicle is improved. And the correctness of signal receiving is improved.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a control method and a controller for TDOA-assisted RID signal reception. Background technique [0002] The rapid development of the UAV industry makes the flight management of various UAVs, especially for the flight control of UAVs near targets such as airports and important sensitive places, imminent. RID (Remote ID) is a key technical detail in the ASTM F3411-19 standard for flight control of UAVs. It is an important part of the current control of UAVs by relevant departments, so it is very important to receive RID signals correctly. Ensuring the correct reception of UAV RID signals under complex terrain and dynamic flight conditions is an important part of UAV control. [0003] In the prior art, methods such as antenna array and signal enhancement are generally used to enhance the reception of UAV RID signals, but this method needs to rely on the accurate positioning ...
