Abstract

The invention relates to a quasi-generating unmanned aerial vehicle inducing method and system, belongs to the technical field of satellite navigation, and solves the problem that the prior art cannot achieve fast, efficient and concealed target unmanned aerial vehicle navigation and deception. The system includes: a signal receiving unit for receiving and analyzing real satellite navigation signals of all visible satellites to obtain their ephemeris information; a target tracking unit for collecting the current position of the target UAV in real time; a strategy generating unit for Ephemeris information, the current position of the target UAV and the expected position at the next moment, the output pseudo-range delay, the real satellite navigation signal of the selected visible satellite for delay, and the transmission power for power enhancement; induction signal The generating unit is used for generating a radio frequency signal based on the real satellite navigation signal of the selected visible satellite for delay; and sequentially delaying and enhancing the power of the radio frequency signal to generate an inducement signal, and transmit the inducement signal to the target UAV.

Description

technical field [0001] The invention relates to the technical field of satellite navigation, in particular to a method and system for inducing a quasi-generating unmanned aerial vehicle. Background technique [0002] In recent years, UAV technology has developed rapidly and is widely used in many fields such as emergency rescue, military operations, remote sensing mapping, agricultural plant protection, etc. It has great application value in national defense construction and economic development. However, due to the small size and simple control of drones, they are easily exploited by criminals. There have been many incidents of drones illegally entering sensitive airspace around the world. Therefore, effective countermeasures must be taken. [0003] The UAV induction system sends false satellite navigation and positioning signals to the target UAV to induce it to deviate from the preset motion trajectory and gradually reach the designated area. It is an effective means of ...
