基于遭遇点预测的比例导引与多平台接力制导交接律设计

为实现舰艇编队的区域防空,要求舰空导弹具有超视距协同制导能力。针对这一问题,在比例导引剩余时间估计的基础上,给出了基于遭遇点预测的舰空导弹超视距比例导引制导方法。在多平台接力制导过程中,为避免由多种误差因素造成的导弹控制指令的突然变化,引进平滑因子,在给定时间内完成制导指令的平滑交接。仿真结果验证了设计方法的有效性。

Design of the Proportional Navigation Based on Hit Point Prediction and Multi-Platform Relay-Guidance Transfer Law

To achieve the regional fleet air defense,the ship-to-air missile was requested to guide with BVR capabilities together. According to this problem,on the basis of the proportional navigation estimated time remaining,the ship-to-air missile over-horizon proportional navigation method was given based on hit point prediction. In the multi-platform relay guiding process,in order to avoid the error by a variety of factors contributing to sudden changes in the missile control instructions,the smoothing factor was introduced in a given period of time to complete a smooth transfer of guided instruction. Simulation results demonstrated the effectiveness of this method.
