A novel jamming technique is proposed to generate effective jamming against synthetic aperture radar (SAR) to protect multiple displaced targets given availability of limited jamming power, which is a typical situation. A smart noise jamming technique is proposed using digital radio frequency memory (DRFM). It allows the jammer to achieve effective jamming in such situation by condensing its power on specific sensitive areas on the SAR image to cover certain targets. This technique utilizes, in its core, the convolution noise jamming which has proven to allow high level of controllability. A closed form of the multichannel convolution noise jamming (MC-CNJ) governs the effect on the SAR receiver is introduced. Parameters introduced to control each jamming channel independently, to produce noise patches with determined size and position in range and azimuth dimensions. Through the proposed technique, a high intensity noise patches are formed to skin limited areas instead off scattering the jamming power over the whole SAR image. The results of simulation using the Matlab clarify the performance of the new jamming technique effect on a real SAR image.
