Description
Summary:This article provides a feasible solution to locate target in non-line-of-sight (NLOS) area, which includes a robust NLOS target positioning algorithm based on millimeter-wave radar (MMW-radar) and corresponding hardware system design based on quad-copter. At the hardware level, an unmanned aerial vehicle (UAV) equipped with MMW-radar is developed, and an experimental environment under strong reflection condition for simulating urban environment is built in this paper. At the algorithmic level, a NLOS target positioning method for urban areas based on MMW-radar operating in the 77GHz frequency band is utilized to detect hidden targets. Specifically, this paper provides methods to eliminate clutters, associate existing traces, and build traces. Furthermore, a geometric correct method is designed to map preliminary locating results into the real environment. Finally, our comparative experiment shows the proposed method can locate NLOS target accurately on UAV platform, and filter various clutters well.
