Abstract：In Through-the Wall Imaging (TWI), the clutter, because of its great energy, has great effect on the detection of the targets. For the purpose of clutter suppression, Factor Analysis (FA) method is applied to TWI data. Besides, a new evaluation criterion, image contrast, for selecting the proper factors is introduced. To validate the method experimentally, a set of through-the-wall experiments in an anechoic chamber are designed. The experimental results indicate that the technique based on FA and image contrast can efficiently suppress the clutter without a priori knowledge about targets.
