Through‐the‐wall radar has been used in rescue missions, behind‐the‐wall targets detection, surveillance and reconnaissance etc. However, through‐the‐wall radar encounters two major problems in complex environment. One is that the refraction of the unknown wall would distort the through‐the‐wall image. The other is that the multi‐reflection between wall and walls as well as wall and targets would lead to a lot of fake targets. To solve these problems, a multi‐path suppression algorithm is proposed in this study. The simulation results show that proposed algorithm can automatically estimate the thickness and dielectric parameter of the unknown wall and give an undistort image, and remove the fake targets due to the multi‐path effect.
