Abstract:

Through the analysis of the influence of deception signals on the target receiver clock frequency drift, a receiver clock frequency drift model is established in uniform circular motion when the target receiver is cheated. Then the correlation values between clock frequency drift and cosine function are calculated. By monitoring the normalized circle correlation values we can successfully detect deception jamming signals, and effectively prevent the occurrence of a false alarm at the same time. Through analyzing related peak phase and related processing calculated we can get the azimuth and elevation angles of disturbing source. Simulation results show that the azimuth and elevation angle estimation error is within 1°. This algorithm is very feasible, and has very important theoretical and practical values.
