In this paper, a novel target height finding method based on the robust beamspace transformation is proposed in ground-based air-surveillance radar applications. Compared with the conventional multipath height finding techniques, all diffuse reflected multipath signals are considered as the interference signals and cancelled via beamspace transformation in our method. Measured data from an experimental 3D air-surveillance radar are used to demonstrate the performance of the proposed method. Experimental results show that the proposed method provides reliable height finding performance and can be applied to the ground-based air-surveillance radar systems.
