摘要

根据初始瞄准误差、导引头角噪声、目标闪烁的特点,分别建立对应的比例导引制导模型,广泛采用伴随法,得到其伴随模型,并利用无量纲归一化方法,得到无量纲脱靶量与制导系统各参数的关系,仿真结果表明制导系统的脱靶量与有效导航比、系统阻尼、带宽与脱靶量密切相关,低阻尼、低带宽对制导系统的脱靶量有不利的影响;由角噪声、目标闪烁引起的脱靶量并不随末导时间的延长而减小趋于零,而是趋于稳定的常值。

Abstract

The PN guidance model was established with the three error sources, heading error, angular noise and glint effect. Base on the method of adjoint and non-dimensional method, the adjoint model of the PN-guidance was obtained and the expression of non-dimensional miss distance was deduced. It is concluded that the induced miss distance has a close correlation with navigation constant N, system damp and bandwidth while a low system damp and bandwidth has adverse influence on miss distance. The induced miss distance does not decrease to zero but increase to a constant value with the increasing flight time of the engagement when angular noise and target glint was introduced in the system.

Key words： heading error; angular noise; target glint; method of adjoint; proportional navigation; miss distance
