Abstract

Abstract

A space coning target has the typical micro-motion. A novel parameters estimation method for space coning target based on two-aspect range profile sequences is proposed in this paper. The parameters of space coning target include precession parameters and structure parameters. First, this paper analyzes the trace of the radar elevation angle when the target is in free phase. Using the established precession model, the equation for the projections of the targets scatters onto the Radar Line Of Sight (RLOS) is derived. Then, analytical solutions of the parameters are obtained based on the two-aspect range profile sequences. Ballistic curve is introduced to solve the problem that the estimation of half cone angle requires high Signal-to-Noise Rate (SNR). Finally, the experiments verify the effectiveness of the proposed method by using electromagnetic data.
