Multiple Targets 3D Detection Based on FMCW Radar

A radar system for multiple targets 3D detection is presented. Based on FMCW radar, this paper proposes a kind of orthogonal receiving antenna array in horizontal and vertical dimensions respectively and introduces the detection method of range, velocity, azimuth and elevation 3D information. Furthermore, this paper solves the mismatching problem of the parameters in two dimensions under the situation of multiple targets using the proposed FFT-MTD-DBF method and decreases the false alarm rate. Finally, 3D detection results of multiple targets are obtained through simulation.
