基于助推段防御和比例导引法,分析了拦截弹与目标导弹的相对运动关系并给出了比例导引方程;采用差分法分析了拦截弹与目标导弹的位置关系、构建了数学模型并推导了拦截弹的差分方程;以拦截时间和拦截弹道为研究对象,分析了拦截弹的速度和比例系数对拦截时间和拦截弹道的影响,并对比例导引法的拦截弹道进行了三维仿真。仿真结果表明,助推段防御使用变系数比例导引法,可有效缓解拦截时间与拦截弹机动性之间的矛盾。
Based on the boost section defense and proportional guidance method, the relative motion between the interceptor and the target missile is analyzed and the proportional guidance equation is given. The difference between the interceptor and the target missile is analyzed and the mathematical model is constructed. Based on the interception time and interception trajectory, the effects of interceptor velocity and proportional coefficient on the interception time and interception trajectory are analyzed. The interception trajectory of the proportional guidance method is simulated by 3D simulation. The simulation results show that the use of variable coefficient proportional guidance method for boost segment defense can effectively mitigate the conflict between the interception time and the interceptor missile mobility.
