Seamless rapid unmanned aerial vehicle navigation deception system and method

Abstract

The invention proposes a seamless rapid unmanned aerial vehicle navigation deception system. The system comprises a radar monitoring subsystem used for monitoring the position of an unmanned aerial vehicle in real time, and obtaining a time system of the unmanned aerial vehicle at the moment and position information of the unmanned aerial vehicle under a current geodetic coordinate system; a computing platform used for calculating information of a pseudorange between the unmanned aerial vehicle at the current position and each real visible star on the sky according to an ephemeris parameter and the position information of the unmanned aerial vehicle; a deception signal generation subsystem used for simulating and generating a deception signal in real time according to the atomic time corresponding to an internal receiver of the unmanned aerial vehicle at the moment, the position information of the unmanned aerial vehicle and the true visible star pseudorange information; and a signal transmitting subsystem used for sending the deception signal to a target unmanned aerial vehicle. According to the seamless rapid unmanned aerial vehicle navigation deception system provided by the invention, by generating artificial stars with the same pseudodistance from the unmanned aerial vehicle to the star on the sky, the deception signal can be quickly and seamlessly accessed to the receiverof the unmanned aerial vehicle, and the receiver does not need to be subjected to the processes such as loss of lock and recapture, therefore, the access time is greatly shortened and the deception efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of navigation attack and defense, and in particular relates to a seamless fast unmanned aerial vehicle navigation deception system and method. Background technique [0002] In recent years, the UAV industry has developed rapidly, and the application of UAVs has exploded in both military and civilian fields. Several incidents of black-flying drones interfering with flight flights have resulted in alternate landings, hundreds of flight delays, and tens of thousands of passengers being blocked and stranded at the airport. Therefore, from the perspectives of urban airspace security, terrorism prevention, and maintenance of public security, it is urgent to take strong control measures against black-flying or malicious black-flying UAVs. [0003] At present, most of the control and interference methods for black flying drones use high-power radio suppression interference and navigation signal deception. Although...
