A Novel Method for Detecting Slowly Moving Targets in Side-looking SAR Based on the Radon Fourier Transform

Inhalt:
This paper proposes a novel method for detecting slowly moving targets in side-looking SAR using the Radon Fourier Transform (RFT). The algorithm first carries out range compression and system range cell migration correction to achieve range matching filtering and remove system range migration. Next, in the RFT processing, range walk removal and quadratic phase error compensation are used to avoid range interpolation and to compensate residual phase error. Slowly moving targets are then well-focused in the range-Doppler domain. Simulation results are performed to verify the effectiveness of the proposed method.
