Multi-Component Target Detecting of SAR Based on Improved WVD-HT for Frequency-modulation Jamming

摘要：

Multi-component target detecting and parameter estimation of SAR are of most significance for military applications.In practice SAR is interfered by ground clutter and artificial jamming. The jamming can be restrained by multi-component target detecting that adopts the smoothed pseudo Winger-Ville distribution. Meanwhile,the cross terms of the Winger-Ville distribution can be smoothed. Combine Hough transform the time-frequency concentration is improved and better precision of parameter estimation will be obtained.Multi-component target detecting and parameter estimation by the smoothed pseudo Winger-Ville distribution and Hough transform for frequency-modulated jamming are simulatedIn This paper. The method proved to be efficient for target detecting and parameter estimation of SAR.
