Recognition of target in through wall imaging using shape feature extraction

This paper presents a novel shape recognition approach for analysis of through wall images. The developed algorithm consists of image formation, processing for image enhancement, feature extraction and shape recognition. In this paper, ultra wideband step frequency continuous wave (SFCW) radar is used to collect C-scan data from which images are obtained to give the approximate shapes of target. Results on experimental data show that the proposed algorithm exhibits promising performances both in terms of target detection and recognition.
