<FONT face=Verdana>By analyzing the limitation of the traditional two-dimensional LDA
a new SAR image recognition algorithm based on two-dimensional subclass discriminant analysis is proposed in this paper. First
image preprocessing of SAR image is performed
which includes image aligning and power transformation. Then image Euclidean distance NN-Clustering is proposed to divide the datasets per class into multi-subclasses
and feature matrix is extracted by two new methods
i.e. 2DSDA and Alternative-2DSDA. Finally
a nearest neighbor classifier is employed to classify the extracted features. Experimental results with MSTAR dataset verify the correctness and effectiveness of the proposed method.
