摘要	Accurate and loss-free extraction of human echo signals from the hidden environment is of great importance in military, disaster relief and medical fields, and is also a hot spot for research in the related field of radar through walls. When detecting human targets through walls, noise and hidden environment objects such as walls tend to attenuate electro-magnetic waves to a large extent, which leads to the inability of radar to detect human targets accurately. In this paper, in order to remove the interference of wall echo and environmental noise from the echo signal, a pre-processing method of human echo signal of through-wall radar with improved PCA and MTI fusion algorithm is proposed. Firstly, SVD is used to pre-process the simulated noise-plus-interference echo signal, and then it is verified by the actual collected data, and the simulation results are more satisfactory, but the interference from the wall cannot be completely removed in practical application. In response to the above problem, the improved PCA and MTI fusion algorithm was used for pre-processing, and the simulation results and actual data showed that the ambient noise was suppressed and the wall interference was also removed. © 2021 IEEE.
