Study and realization on the real-time range migration correction algorithm for SAR

The paper analyses the echo model and the theory and processing method of range migration of synthesis aperture radar (SAR), by imposing a real-time motion compensation algorithm based on range Doppler(RD) algorithm which aims at real-time signal processing, as well designing and realizing a real-time imaging processor which possesses the ability of motion compensation by adopting large scale parallel DSP processing technique. The accuracy of the algorithm and real-time processing ability of the processor are validated through field experiment.
