摘要：

Detecting signals in areas where there are many obstacles, such as Non-Line-of-Sight (NLoS) is difficult, in conventional radar systems. In this study, we investigated a radar system for detecting pedestrians in NLoS using a secondary radar system and oversampling of the received waveform in an on-board device; then, measured the range and direction detection properties. We analyzed the results of these experiments that were measured in a large anechoic chamber with metal walls to emulate NLoS conditions. The direction of the target in the NLoS was successfully detected. The proposed scheme was able to measure the distance to the target within an error margin of 5 m.
