Abstract: A new method is proposed for direct wave and wall clutter suppression in through-wall surveillance using spread spectrum radar.
It is seen that the direct wave and wall clutters can be mitigated significantly and the target information can be enhanced greatly and a low-cost ADC could ...

Suppression of Direct Wave and Wall Clutter for Through-Wall Imaging by Spread Spectrum Radar. Zhang, Xuehui; Wu, Daocheng; Xi, Xiaoli; Song, Zhongguo. 2015.
It is observed that ICA has better capability to remove the clutter in comparison to other applied techniques; especially it is found that ICA has a capability ...

The basic CLEAN algorithm has been improved to get better performance when the characteristic of direct wave is varied with the time. The direct wave has a ...
It has been demonstrated that RPCA is an effective clutter removal method in through-wall imaging applications [21,22,23,24]. For TWI radar, as the number of ...
