Shared aperture jamming
Webb4 nov. 2004 · A study on active jamming to synthetic aperture radar Abstract: Synthetic aperture radar (SAR) has its own special features different from conventional radar. It … 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.
