Problems solved by technology

[0002] In recent years, with the development of science and technology, a large number of low-cost micro drones have flooded into the market, and the total annual sales volume has reached tens of thousands of units; the main purpose of civilian drones is aerial photography, and the working frequency band is 2.420~2.4835 GHz, the center frequency is 2.45GHz; however, there is no perfect high-precision system for the capture of this type of UAV. Once it is maliciously used by terrorists, the consequences will be unimaginable. It is of great significance to quickly and effectively realize the high-precision capture function of the civilian UAV capture system

Abstract

The invention discloses a civil unmanned aerial vehicle capture system based on the ISM frequency band, which includes an antenna, an interference module, and a feed source system for receiving external signals received by the antenna, and performing branching processing on them to obtain a three-way splitting signal. signal and transmit it, and used to receive the interference signal, process it, obtain the interference transmission signal and transmit it to the antenna; the frequency conversion module is used to receive the three-way branch signal, and down-convert it to obtain the azimuth signal and the elevation signal and Σ signal and transmit; the frequency measurement module is used to receive the Σ signal, detect and measure it, obtain the measurement signal and transmit it; the tracking module is connected with the frequency conversion module and the frequency measurement module, and is used to receive the measurement signal and azimuth signal , pitch signal and Σ signal, and correct and measure them to obtain the azimuth angle signal and pitch angle signal and transmit them; and the server is used to receive the azimuth angle signal and the pitch angle signal, and control the azimuth and pitch of the antenna according to it horn.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to an ISM frequency band-based capture system for civilian unmanned aerial vehicles. Background technique [0002] In recent years, with the development of science and technology, a large number of low-cost micro drones have flooded into the market, and the total annual sales volume has reached tens of thousands of units; the main purpose of civilian drones is aerial photography, and the working frequency band is 2.420~2.4835 GHz, the center frequency is 2.45GHz; however, there is no perfect high-precision system for the capture of this type of UAV. Once it is maliciously used by terrorists, the consequences will be unimaginable. It is of great significance to realize the civil UAV capture system that can quickly and effectively realize the high-precision capture function. Contents of the invention [0003] Aiming at the above-mentioned deficiencies in the prior ...
