Abstract: SAR image target recognition is a key step in the application of SAR image.For the existing of speckle in SAR image，It can’t be recognized well with traditional methods.According to the advantages of invariant moments extraction and support vector machine（SVM） classification，an efficient method of SAR image target recognition is proposed.In the experiments of recognizing planes and tanks，better results have been obtained with this new method.
