A Non-side-looking Range Compensation Method for MIMO Radar
Abstract— The loss for degree of system freedom and mismatch of prior information based on registration
based compensation method will result in a decline in the computation performance. In order to solve the
above problems, an improved method is proposed where sparse recovery theory is applied instead of the
sub-aperture smoothing operation. Firstly, it combines sparse recovery algorithm with MIMO radar system
whose single frame data are equivalent to multi frame data of the phased array. Then the super resolution
clutter space-time spectrum is gotten by utilizing the sparse recovery. After that the transition covariance
matrix is calculated. Finally, the clutter covariance matrix is reconstructed by Capon spectrum. Compared
with the conventional RBC (Registration Based Compensation) method, the method proposed doesn’t depend
on sub-aperture smoothing operation and prior information. In addition, it is also steadier when the sensor
error exists. The experimental simulation demonstrates the correction and feasibility of this method.
