“…Taking into consideration the SAR jamming principle, the jamming effect can be evaluated using three evaluation criteria, i.e. structural similarity index measure (SSIM) [6,11,12], mean absolute difference (MAD) [13,14], and correlation coefficient (CC) [15]. In digital image processing, MAD is a measure of the similarity between image blocks.…”

“…There is a significant saving in the jamming power used by the proposed deception technique than other jamming techniques in [5][6][7][8]. It is possible to implement the proposed jamming technique in practice rather than the other jamming techniques in [5][6][7][8] due to the saving in the jamming power. Fig.…”

“…Fig. 10 shows the comparison of the required jamming power of different jamming techniques in [5][6][7][8] to counter SAR. Different jamming techniques, such as the noise jamming technique in [5], the smart noise jamming in [6], and the complete scene deception in [8] require JSR = 25; 20; 7 dB, respectively, to counter SAR.…”

“…The noise to SAR bandwidth ratio (NSBR) controls the effect of the proposed jamming technique on the SAR output image. In [6], a mathematical model and illustration of the convolution noise jamming technique at the SAR sensor is introduced. Two parameters are proposed to control the convolution noise jamming effect on the output image of SAR sensor.…”

Synthetic aperture radar (SAR) has been widely involved in military reconnaissance and detection of moving targets. SAR active decoy can generate deceptive jamming signal and it can severely affect the content of SAR focused image. SAR range Doppler algorithm (RDA) is considered as one of the most common algorithms utilized in the image formation processor (IFP) in SAR sensors. In this paper, the inverse RDA (IRDA) deception jamming technique and its evaluation criteria on SAR are demonstrated. Mathematical formulations for SAR RDA with and without deception jamming are presented. Matlab simulation and results of SAR RDA under the proposed deception scenario are discussed. SAR point target simulation of the proposed deceptive jamming and false target insertion into real large scene are also introduced. Comparison of the proposed deceptive jamming to signal power ratio (JSR) required to counter SAR with other SAR jamming techniques is analyzed.
