Abstract

A subspace-based auto-paired range and direction-of-arrival (DOA) estimation algorithm without joint diagonalisation for multi-target detection of dual-channel frequency modulated continuous-wave (FMCW) radar are proposed. The proposed method, which is based on signal subspace, exploits the shift invariant structure of the stacked Hankel matrix for the paired range and DOA estimation of multiple targets. To verify the effectiveness of the proposed method, the dual-channel FMCW radar is implemented and its effectiveness verified in an anechoic chamber environment.
