摘要：
A novel delayed conjugated multiplication and sparse decomposition method is proposed to extract the micromotion feature of rotating target with shipborne radar. Combined with the motion mode of shipborne platform, the echo signal of rotating target is analyzed. The influence of ship-swaying is eliminated by delayed conjugated multiplication processing. A set of micro-Doppler (m-D) basis-signals are constructed. Thus after sparse decomposition processing, the m-D features of every scatter are successively extracted according to the coefficients. Finally, the effectiveness of the approach is validated by simulations.
