A Fast Direct Wave Suppression Method by Weighting in Through the Wall Imaging

摘要：

In the through the wall imaging, the direct wave of the wall has strong power, while the echo of the indoor targets has far lower power, which makes serious affect in the imaging and detection of the targets. In this paper, a fast direct wave suppression method by weighting in through the wall imaging is proved. The according of the weight value is analyzed and the block diagram of the algorithm flowsheet is given. The method can suppress the direct wave effectively and improve the target imaging performance with holding the building structure imaging details. At last the elaborate simulation was given via XFDTD software to validate the algorithm effectivity.
