The producing methods of various threaten signals are researched. And the model of the dense and complex radiofrequencypulse signals is founded on the analysis of single radar signal.
Firstly, the obtained radar signal radiofrequency, pulse width, repeat frequency are composed to get a combined probability assignment function of radar parameters by applying D-S method.
In the paper, digital radiofrequency memory (DRFM) is applied to airborne radio fuze jammer to jam pulse distance-detecting fuze and pulse Doppler fuze.
