Compensation method for intensity difference of wall images

For through-wall-radar imaging of building layout, the intensity difference of multi-layer wall images caused by wall propagation attenuation makes it impossible to express the building layout accurately. This paper presents a method to compensate the intensity difference. First, we confirm the existed data connected domains in each single-view layout image. Then the compensation rates of these domains are achieved and the intensity compensation is performed. Additionally, four single-view layout images are fused to form one panorama layout images through M-N-K detector, which further demonstrates the performance of compensation. The XFDTD simulation validates the proposed method.
