| 摘 要： | 捷联导引头在结构上与弹体固连,由于耦合有弹体角运动信息,从而不能直接得到比例导引所需的制导信号.针对采用相位干涉仪制导的旋转导弹,分析了相位干涉仪的测角机制,探讨了弹体角运动解耦原则.最后,提出了一种采用动力陀螺实现弹体角运动解耦的可行性方法,并易得到比例导引所需要的制导信号.仿真结果表明,该方法可以很好地隔离弹体角运动的影响,去耦效果良好,具有一定的工程可行性.

| Abstract: | As strapdown seeker is fixed on the missile body,the guidance signal for proportion navigation law can not be attained directly.And the outputs of strapdown seeker are not appropriate to be directly used in the control system of the missile,for it couples with the missile body angular motion,Aiming at a strapdown seeker using RF interferometer for guidance,the angle measure principle of phase interferometer is analyzed,and the decoupling principle from body angular motion is advanced.Finally,a decoupling me... |
