Some apertures will be shared for communications, radio … WebbJamming of synthetic aperture radar (SAR) is more difﬁcult than the conventional radars because of its high processing gain. The defocusing of fake or virtual scatterers is the main problem that any jamming technique needs to tackle. An algorithm based on fractional Fourier transform is proposed for the efﬁcient jamming of SAR.
