Abstract

Abstract

The micro-Doppler (m-D) effect is introduced for the Multi-Input Multi-Output (MIMO) radar techniques in the paper. Taking rotating target for an example, the m-D effect is analyzed and the parameterized expression is deduced in MIMO radar which transmits OFD-LFM (Orthogonal Frequency Division Linear Frequency Modulation) signals. An algorithm for three-dimensional micro-motion feature extraction is proposed, which extends the m-D signature extraction from the micro-motion projection in Line-Of-Sight (LOS) to the three-dimensional micro-motion feature. By taking advantage of the multi-view of MIMO radar, the three-dimensional micro-motion features are obtained by solving nonlinear multivariable equation systems. Simulation results validate the effectiveness and robustness of the algorithm.
