Abstract:

Target surveillance in urban environment is important in various applications, such as urban battles, rescues and antiterrorism. Due to the complex urban environment, targets are often hidden in non-line-of-sight (NLOS) areas formed by building structures, such as blind spots on street corners. In this case, the traditional through-wall radar using electromagnetic wave penetration characteristics is unable to detect the target in the NLOS area. Different from the traditional through-wall radar, a NLOS detection method based on the diffraction and reflection characteristics of electromagnetic wave appeared and is concerned. Specifically, this report will analyse the diffraction and reflection propagation mechanism of electromagnetic waves in uniform medium space, and demonstrate the multipath propagation model of electromagnetic waves in different building layouts with electromagnetic simulation software. In addition, several NLOS target location algorithms and experimental results based on the DOD/DOA distribution characteristics of multipath and Range-Doppler (RD) topology relationship of multipath are presented.
