成象制导导弹自适应变焦系统设计及目标被动测距和测速方法研究

ON THE DESIGN OF ADAPTIVE ZOOM SYSTEMS AND PASSIVE DISTANCE AND VELOCITY MEASUREMENT FOR IMAGE GUIDED MISSILES

典型的成象制导导弹一般不安装目标测距装置，使导弹变焦系统控制回路具有参数不确定性质。本文采用模型参考自适应控制方法解决了变焦控制系统的综合问题。另外，通过引入充分激励信号，实现了目标的被动测距和测速，为导弹采用最优制导律提供了可能性。最后给出一设计实例，证实了该方法的正确性。

No distance measuring devices are installed in a typical image guided missiles.This leads to uncertain of parameters in the zoom control loop of the missile.This paper uses the model-reference adaptive-control method in synthesising the zoom control system.Besides,the passive distance and velocity measuring of targets is realized throush the use of sufficient exciting signals.Finally,a design example is given to demonstrate the validity of the proposed method.
