半主动导引头弹目多普勒频率对引战配合影响分析

半主动制导防空导弹为现代重要的防空武器,充分利用导引头信息逼近最佳引信战斗部配合是当前研究的热点问题。在弹目大俯冲角交会姿态下,半主动导引头提供的弹目回波多普勒频率折算的弹目相对速度大小与真实值误差偏大,严重削弱引战配合效果。本文给出弹上计算机提供的速度误差的数学模型,分析弹目多普勒频率的成分频率,并通过引战配合仿真试验论述不同俯冲角对引战配合的影响。

Analysis of the Missile-to-target Doppler Frequency Impact on Fuze Warhead Matching in Semi-active Homing Seeker

The technique of optimum fuze warhead matching,approximated by making full use of guidance information from semi-active homing seeker,is a hot spot of current research on semi-active homing antiaircraft missile which is an important antiaircraft weapon at present.A significant error,which is going to have a severe negative effect on fuze warhead matching,is found herein with the missile-target relative velocity calculated by the Doppler frequency of target return under the rendezvous attitude condition of h...
