Research On Jamming Technology To Synthetic Aperture Radar

The technology of most common radar imaging is Synthetic Aperture Radar (SAR) imaging. Recently, airborne SAR imaging and spaceborne SAR imaging are widely used. Under the same signal to noise ratio condition, the resolution of the conventional radar is too far behind to catch up with that of SAR. Therefore, it is necessary for us to analyze the SAR system, based on which we can research on different jamming waveform to make a better implementation of SAR jamming.Firstly, the system of SAR and theory of imaging are analyzed in the dissertation, because of the complexity and difficulty of SAR jamming, aiming at the changes of the purpose and efficiency of jamming, matching jamming system is put forward as an efficacious jamming system to SAR, furthermore, some jamming waveform is dwelled on and the evaluation criterions of SAR image and its jamming image are also introduced. Secondly, a computer simulation model with Matlab is set up based on the theory analyzed. Then some jamming simulations and jamming evaluations on the accomplished simulative platform are made as well as the jamming simulation and jamming effect evaluation with jamming directing error.
