In synthetic aperture radar (SAR), long integration time may induce range migration and Doppler frequency migration of a received signal, which may degrade the SAR imaging performance of ground moving targets. Most of the conventional algorithms deal with the problems of range migration and Doppler frequency migration based on parameter searching. However, the exhaustive searching of target motion...
When the synthetic aperture radar (SAR) imaging is applied to observe a ground scene containing a ground moving target, the moving target image will be typically smeared due to the range cell migration and Doppler spectrum broadening caused by target motions. To eliminate these motion effects, a novel algorithm for ground moving target imaging, which is based on an improved axis rotation-time reversal...
