A method which discriminates the coherent dual-source angle deception interference by using the relative difference between the co-polarization and cross-polarization components of target and interference is proposed. A model of mono-pulse polarization radar echo is established, and the co-polarization and cross-polarization echoes of the sum and difference beams are obtained. A statistic to distinguish the existence of coherent dual-source interference is constructed by using the difference between the interference and the radar target response function in the different polarization channels. A certain confidence level threshold is given according to the measured data of typical warhead and aircraft target and the simulation of coherent dual-source interference. The measured data obtained in darkroom and the computer simulation show that the algorithm is feasible and valid. [ABSTRACT FROM AUTHOR]
