摘要：
After clutters suppression, the feasibility of applying compressive sensing (CS) in through-wall imaging (TWI) using spread spectrum (SS) radar is analyzed. Then CS is compared with the conventional back projection (BP) method in TWI. Results show that it is feasible and very effective to use CS to image the targets behind the wall with SS radar. Furthermore, compared with BP imaging, although the number of observation points using CS method has decreased by 67% and the data store using CS also has declined by 60%, the location accuracy of targets using CS is much higher than that using BP. This will lower the cost of hardware significantly and shorten the recording time greatly.
