Modeling of a strike formation with coherent self-protection jammers

This paper proposes a simple model for simulating quasi-coherent electronic countermeasures using multiple self-protection jammers. By studying the effects of time-difference of arrival between multiple signals at the radar receiverpsilas matched filter output, the probability of coherence is defined for determining probability of survival in mission planning. A theoretical derivation for probability of coherence between jamming pulse signals is postulated and the theoretical data is compared with empirical data extracted from flight simulation. The method is applied to a study of various tactical flight formations with respect to the victim radar. The proposed method allows one to determine probability of survival for the multiple jamming case by simply scaling established probabilities for the single-ship jamming case.
