捷联多模导引头弹体角运动解耦设计

Decoupling Design of Strapdown Multimode Seeker-body Angular Motion

捷联导引头输出的信号中耦合有弹体姿态角运动信号,不宜直接用于弹体控制。文中采用直接安装在导引头上的速率陀螺输出的弹体角运动信号对雷达输出信号进行解耦,并针对多模导引头给出解耦电路。

The output of strapdown seeker is not appropriate to be directly used in the control system of the missile, for it couples with the missile body angular motion. This article presents a decoupling method, which uses the decoupling signal from the rate gyroscope specially installed on the seeker, for the radar output decoupling. Meanwhile a practical circuit against multimode seeker decoupling is also presented.
