Ground Moving Target Indication Based on Optical Flow in Single-Channel SAR

An algorithm based on optical flow is proposed to detect a ground moving target via the single-channel synthetic aperture radar. First, the signal models of uniform moving targets are established and classified into three types. Next, the Doppler spectrum is divided to generate a multilook image seq...
