Problems solved by technology

The disadvantages of the system described in this patent are: 1. The cost of an independent GPS spoofer is relatively high; 2. The entire system uses the control center as the data interaction center, and the actual deployment of the system is complicated; 3. The jammer and the GPS spoofer are independent of each other , redundant design on the antenna; 4. The target controller has nothing to do with the overall technical solution of the GPS jamming and deception system
The disadvantages of this method are: 1. The direct control signal between the UAV and the remote controller is not cut off, the UAV deception for GPS programming flight is effective, and the UAV deception for real-time controlled UAV is invalid; 2. The method has a dynamic adjustment stage , there may be multiple cyclic processes. In practical engineering applications, firstly, there is a certain reaction time for the UAV to relocate the spoofing signal, and secondly, it is necessary to observe the position and movement information of the UAV, which depends on radar or radio spectrum. UAV position detection equipment, and these devices can only generate the corresponding track after the UAV has been flying for a period of time. These two points lead to a long dynamic adjustment phase. In actual use, the decoy time is too long to make this method practical. lower
However, the system has the following disadvantages: 1. Due to the use of passive positioning, the system cannot detect drones that do not emit electromagnetic waves, such as programmed flight; 2. Since the flying remote control is usually on the ground, the remote control signal has multi-path transmission , Secondly, the remote control signal emitted by the remote control is directional and may not be detected by passive radar. Therefore, there are problems such as difficulty in locating the pilot and ambiguity in positioning. Ground crew carry out searches with portable radio spectrum detectors, complicating law enforcement
However, the common problems at present are: 1. The equipment integration of the anti-UAV system is not high enough, and it is just a simple patchwork of existing equipment; 2. The UAV flight control system has gradually introduced anti-GPS deception algorithms, and the difficulty of GPS deception is gradually Increased height; 3. The problem of difficult identification and capture of drone pilots has not been resolved

Description

technical field [0001] The invention relates to the technical field of electromagnetic countermeasures, in particular to an unmanned aerial vehicle interference deception system and an unmanned aerial vehicle defense system. Background technique [0002] In December 2011, a U.S.-produced RQ-170 Sentinel drone was captured when it invaded 250 kilometers of Iranian airspace. An Iranian engineer described the process of capturing the drone: first shielding the drone's communication lines, cutting off its connection with the ground control center, and at the same time interrupting its secure data connection with the GPS satellite, forcing it to enter Automatic navigation state; this is the use of forwarding deception jamming technology to package wrong information into a seemingly reliable GPS signal, and then grasp the precise landing altitude and latitude and longitude data, so that it can land at the designated place, without cracking the drone during the whole process Remot...
