Three-dimensional Micro-Doppler Signature Extraction in MIMO Radar

摘要：

In traditional monostatic radar, only the micro motion signatures projected in line-of-sight (LOS) could be extracted from the targets echoes. which are insufficient for accurate target recognition due to the target-aspect sensitivity. In this paper, we propose an algorithm for the three dimensional micro-Doppler signature extraction using the multi-input multi-output (MIMO) radar technique. The micro Doppler effect in MIMO radar induced by rotation is analyzed. Profited from the multi-view of MIMO radar, the three dimensional micro-motion features, which are not sensitive to the targets aspect anymore, are obtained by solving nonlinear multivariable equation systems. Simulations are given to validate the effectiveness of the proposed algorithm.
