Peak Feature Extraction of Target in SAR Image

Abstract:

Peak feature extraction is an important section in SAR automatic target recognition (ATR). A novel method for peak feature extracting has been proposed, and an extended peak characteristic is given. Directly dealing with the peak model, the feature parameters is extracted by means of weighted least-square fitting using neighborhood information; a detailed error analysis for feature parameters extraction imposed by noise has also been carried out, and an analytic variance expression is given. In the end, some experimentation are done using simulated data, domestic real airborne SAR data and MSTAR data, and the results verify the validity and accuracy of the method.
