Abstract

The present invention provides a control method, device and system for TDOA-assisted RID signal reception, wherein the method includes: obtaining a positioning signal, the positioning signal is obtained by N TDOA devices detecting the designated signal of the target drone, wherein N≥ 3: According to the positioning signal, determine the UAV position information of the target UAV at M moments; where M≥1; determine the RID receiving antenna according to the UAV position information at M moments and the antenna position information of the RID receiving antenna angle information; according to the angle information, adjust the signal receiving angle of the RID receiving antenna; obtain the RID receiving signal received by the RID receiving antenna, the RID receiving signal is obtained by the RID receiving antenna receiving the RID sending signal sent by the target UAV, the present invention The signal receiving capability of the RID receiving antenna is improved, the bit error rate of demodulation is reduced, and at the same time, the signal receiving range of the RID receiving antenna is expanded.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a control method, device and system 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. Due to the long distance between the UAV and the RID receiving equipment or the attenuation of the RID signal caused by the complex terrain of the city, it has become a difficulty for the related system to operate well. [0003] In the prior art, methods such as antenna array and signal enhancement are generally used for receivin...
