Abstract
In this study, we analyzed the deceptive jamming performance of a synthetic aperture radar (SAR). Four cases were considered: (1) time synchronization between the SAR and the jammer, (2) the number of fast Fourier transform (FFT) points that the jammer can use, (3) the minimum signal processing time of the jammer, and (4) the minimum feasible time interval in the jammer. To analyze the effectiveness of each case, the satellite-borne SAR and jammer simulation environment were used. From the results, it was confirmed that the four cases of jammer performance can affect the false SAR image quality, leading to the deterioration of its deceptive jamming performance. Therefore, we suggest that an analysis of the ability of the jammer is necessary for implementing more sophisticated SAR deceptive jamming signal processing.
