摘 要:
为了研究基于空间锥体目标进动特性的识别方法，通过对空间锥体目标的弹道建模，分析了进动锥体目标姿态角变化，引入平均视线角变化对回波RCS的影响，推导了空间锥体目标相对雷达波的姿态角计算公式，分析RCS随时间变化关系，通过回波RCS序列估计进动周期及进动角参数，以惯量比为特征，提出弹头和诱饵的识别方法，仿真试验证明了算法的有效性。[著者文摘]

Abstract:
In order to research on nutation of cone-shaped spetial target, the ballistic trajectory model was introduced. The influence of Radar Scatter Cross caused by the transformation of average-visual angle is analyzed. The attitude angle expression of a precession Ballistic missile is derived, and the trend RCS change with time is analised. Nutation cycle and nutation angle is derived by RCS sequence. Inertia ratio is then used to discriminate warheads and decoys. Finally, a simulation result demonstrates the effectiveness of this approach.[著者文摘]
