Abstract:

A motion model and a micro-Doppler signature generation model for corner reflectors in the sea surface are proposed. Based on the sea keeping theory, considering the sea state and the hydrodynamic coefficient of the carrier, the motion model of the corner reflector is established. According to the radar parameters, the micro-Doppler model of the corner reflectors, due to the roll and heave motion, is derived. Finally, the timefrequency transform is used to analyze the timevarying micro-Doppler features. A number of numerical  examples are presented to demonstrate the effectiveness of the proposed model.
