| Abstract: |
| The detection and positioning technology of concealed non?line?of?sight （NLOS） targets has wide applications in urban street warfare, security, riot prevention and other fields. This article focuses on the detection and locali?zation of a single target in L?shaped non?line?of?sight area. Firstly, the radar deployment location and the detectable area are analyzed. Secondly, a multipath joint detector is designed for the common detectable area. Finally, based on the designed multipath radar application system, experimental verification is conducted by use of the proposed detection and positioning method. Compared with the existing researches, the innovations of our study lie in： the deployment position and detectable area of wide beam millimeter wave radar in L?shaped non?line?of?sight scenarios are analyzed and the reasonable suggestions are given; the proposed multipath joint detector realizes the joint use of multiple paths of different reflection surfaces, for improving detection performance. This article verifies the reliability of the system and the impact of radar position on the detectable area through experiment, and explores the performance improvement of the proposed detector through simulation and experiment. |
