摘要：

For the special azimuth multichannel reconstruction processing of high-resolution wide-swath single-input multiple-output synthetic aperture radar (HRWS-SIMO-SAR) to resolve the Doppler ambiguities, this letter studies the imaging characteristics of conventional SAR Doppler-modulation jamming (DMJAM) in HRWS-SIMO-SAR to provide the theoretical basis for the development of HRWS-SIMO-SAR anti-jamming technology. The theoretical analysis points out that the DMJAM signal will generate equally spaced false targets along the azimuth direction after imaging, and the amplitude of the false targets is decided by the combined sinusoidal function and matched filter loss associated with the Doppler-modulation frequency. The simulation experiments verify the accuracy of the theoretical analysis.
