| 摘要: |
| 隐蔽非直视目标探测和定位技术在城市巷战、安防、防暴等领域具有广泛的应用。本文针对L形非视距区域内单目标的探测与定位问题进行研究。首先，对雷达布设位置及可探测区域进行了分析；其次，针对共同可探测区域，设计了多路径联合检测器；最后，基于设计的多径雷达应用系统，利用所提检测定位方法进行实验验证。与现有研究相比，本文的创新点在于：在L形非视距场景下，对宽波束毫米波雷达布设位置及可探测区域进行分析并给出合理建议；其次利用所提多路径联合检测器将不同反射面的多条路径联合使用，提高了检测性能。本文通过实验验证了系统的可靠性及雷达位置对可探测区域的影响，通过仿真与实验探究了所提检测器的性能改善。 |

| 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. |
