Abstract

The recognition performance can be enhanced using the ISAR target 2D image pre-processed. The image consists of many scatters. The image with holes is disadvantageous for extracting features in automatic target recognition (ATR). An approach of ISAR target 2D image pre-processing is proposed. It contains suppressing the interferential stripes, connecting the scatters and normalizing the mass center. The smoothed image in the center of the picture is obtained. It is tested that the feature of low order moments has a favorable distinguishing.
