针对激光寻的空地导弹激光启动照射时间的精确判定问题,提出了一种基于多维度多项式拟合的时序策略设计方法,所提方法充分考虑了温度、海拔高度以及载机飞行速度等多种因素对激光启动照射时间的影响。结合工程实际,通过特征点多项式拟合的方式实现参数影响的逐层传递,给出了激光制导空地导弹的激光启动照射时间表达式,实现了高精度激光启动照射时间的快速计算。空地导弹的实测飞行数据,验证了本文所提方法的有效性。

Focusing on the problem of precise determination of laser starting irradiation time for air-toground missiles(AGMs),a timing strategy design method based on multi-dimensional polynomial fiing is proposed.The presented method takes various factors including temperature,height and platform velocity into consideration.Influence by the parameters is delivered step by step through feature points-based polynomial fitting,and the expression of laser starting irradiation time for AGMs is given.The high precision time of the laser irradiation starting can also be achieved.The effectiveness of the proposed method has been verified with real flight data of AGMs.
