The micro-motion feature extraction for micro-motion target has attracted great attention in recent years. The micro-Doppler (m-D) effect of rotating target is introduced in the netted radar techniques in the paper. The m-D effects are separately analyzed and the parameterized expressions are deduced in the netted radars that transmit different forms of signals. Making use of the multi-view of netted radar, the parameters of the radars' different forms of echo signals those come from different locations are extracted, the three-dimensional micro-motion features are obtained by solving nonlinear multivariable equation systems. Simulation results validate the effectiveness of the proposed algorithm.
