摘要

摘要: 空间锥体目标在自由段是典型的微动目标。该文研究了基于双视角距离像的空间锥体目标参数估计方法，估计的目标参数包括进动参数和结构参数。首先分析了雷达俯仰角在空间锥体目标自由段的变化情况，并且利用建立的目标进动模型，得到了目标散射中心在雷达视线(RLOS)上的投影方程。然后基于双视角下的距离像序列推导出目标参数的解析解，并引入弹道信息来解决半锥角的估计对信噪比(SNR)要求较高的问题。最后利用电磁计算数据验证了方法的有效性。

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.
