Adaptive Matching Filtering Algorithm for SAR Radar Dispersion Effect Suppression
Spaceborne synthetic aperture radar(SAR)has the advantages of strong penetrability and no limitation of illu-mination.Aiming at the problems of signal distortion,signal inaccuracy,amplitude fluctuation and phase fluctuation caused by dispersion effect in high-frequency band during the commu-nication of spaceborne SAR and ground,we propose a correc-tive matching filtering algorithm based on adaptive filtering,and analyze the characteristics of signal distortion and correct the pulse waveform.The experimental results show that the proposed algorithm can effectively compensate the time delay and phase distortion and correct the pulse signal waveform dis-tortion.
