Principle Analysis of Coherent Two-Point Source Jamming Based on Amplitude Comparison Monopulse

Cross-eye jamming is a kind of coherent two-point source jamming in the true sense, and its main benefit is that it is effective against monopulse tracking radars, which are largely immune to other forms of jamming. The existing analysis of cross-eye jamming mechanism is mostly based on phase-comparison monopulse model, while the amplitude-comparison model and phase-comparison model are widely used in practical application. In this paper, a comprehensive mathematical and experimental study of two-element retrodirective cross-eye jamming under the amplitude-comparison monopulse is established. The jamming mechanism of coherent two-point source jamming is fully verified in typical scenario, and the main factors affecting the jamming performance and their characteristics are analyzed.
