Abstract:

With the development of the synthetic aperture radar （SAR） technology, how to extract and interpret the SAR information is more and more important. The SAR target characteristics analysis for target recognition is studied in detail in the paper. Firstly, the factors which have effect on the SAR target characteristics are analyzed. Secondly, the SAR target characteristics analysis and feature extraction of small targets, line targets, and region tar   gets from SAR images are systematically summarized. Finally, the outlook of SAR target recognition is put forward.

Key words: synthetic aperture radar （SAR）, target characteristics analysis, feature extraction
