Key Region UAV Fusion Immersion Deception Algorithm

In order to solve the problem that deception is difficult due to various anti-interference methods such as autonomous integrity test and parameter rationality test of active UAV, a distributed multi-domain fusion immersion deception algorithm is proposed. The spoofing model of GNSS and the spoofing model of composite navigation system are constructed, the detection principle of least square residual and parameter rationality check is analyzed, and the pseudo-range deviation and pseudo-range rate deviation are calculated, so as to determine the spoofing delay and realize the multi-domain fusion of spoofing signals in time-frequency domain, spatial domain and power domain. The simulation results show that the algorithm can gradually change the location result of the target UAV, and finally successfully deceive the target, and effectively enhance the protection ability of the key point area.
