针对舰空导弹普通中制导律目标拦截时间长和方程计算繁琐的问题,设计了一种舰空导弹拦截目标中制导律。在三维比例导引律、偏置导引律和预测遭遇点导引律基础上,改进提出了基于预测遭遇点的变系数中制导律。对制导律的制导性能和速度响应特性进行仿真实验,结果表明同等条件下改进制导律目标拦截时间更短,速度相应特性更好。仿真实验证明了改进中制导律的有效性。

In order to reduce the target interception time and avoid complex iterative computation of the general guidance law, we designed a variable coefficient target interception midcourse guidance law on the basis of prediction hit according to three dimension guidance law, prediction hit and other guidance laws. Simulation results improved that the target interception guidance law is a practical guidance law which has less time to intercept target and better response to ship-to-air missile speed.
