Joint Multichannel Motion Compensation Method for MIMO SAR 3D Imaging
International Journal of Antennas and Propagation, 2015 The multiple-input-multiple-output (MIMO) synthetic aperture radar (SAR) system with a linear antenna array can obtain 3D resolution. In practice, it suffers from both the translational motion errors and the rotational motion errors.

Superresolution versus Motion Compensation-Based Techniques for Radar Imaging Defense Applications
EURASIP Journal on Advances in Signal Processing, 2010 Radar imaging of noncooperative targets is an interesting application of all-weather high-resolution coherent radars. However, these images are usually blurred when using the standard range-Doppler algorithm, if a long coherent processing interval (CPI ...
