Experimental Study on Along Track Target Velocity Estimation for Multiple Aperture SAR-MTI Configuration
SAR (Synthetic Aperture Radar) moving target along-track velocity estimation method for multichannel system is proposed. The proposed method works on the co-registered multichannel SAR images and employ sub-aperture processing to enhance the robustness to the clutter and noise. The velocity estimation performance of the proposed algorithm is shown through airborne Ku-band three channel SAR experiments, and it has been shown that the accuracy of the along track velocity estimation of moving target at the range of about 2.5km is on the order of 0.2 m/s.
