Abstract :
In this paper, based on auto target recognition (ATR), two kind of feature in ISAR images are extracted: Fourier-transform coefficients feature and wavelet-transform coefficients feature. Three kinds of targets ISAR images were done some recognition study based on the exact nearest neighbor algorithm and those extracted features. Experimental results show these two methods are effective.
