The Similar Clutters Jamming to Wideband SAR Based on Leading of Parameters

Wideband-high-resolution SAR background clutters affect the target detection and classification seriously. Aiming at SARs weakness , the paper puts forward a new matching jamming, which is time, frequency and Doppler fields multidimensional-matching-overcast similar clutters jamming. In the paper, generation of the correlated statistical clutter vectors using zero memory nonlinearity method is developed. Because of the traditional method of using digital frequency memorizer is inapplicable to wideband SAR jamming, the jamming theory based on the leading of parameters and narrowband signals pieceing together technology on wideband jamming realization is researched .Finally, through the Matlab emluator, the paper validates that the method is effectual to jam the wideband SAR.
