相控阵雷达导引头捷联去耦数字平台设计

相控阵雷达导引头是未来导引头发展的一个重要领域,为了消除弹体扰动对导引头测量误差的影响,实现相控阵雷达导引头的捷联去耦,设计了一种相控阵雷达导引头捷联去耦数字平台,采用基于四元数法求取弹体的姿态角,采用相控阵雷达导引头波束扫描稳定算法实现对波束扫描误差的补偿,达到导引头捷联去耦的目的,并在MAT-LAB中对四元数法和波束扫描稳定算法进行了仿真验证,取得了较好的去耦效果,该相控阵雷达导引头捷联去耦数字平台具有原理简单、算法运算量小和去耦效率高的特点。

Strap-down decoupling digital platform design of phased array radar seeker

Phased array radar seeker is an important development realm of the seeker system,in order to remove the measurement error of the seeker from the missile’s movement which will achieve the phased array radar seeker’s strap-down decoupling,the strap-down decoupling digital platform of phased array radar seeker is designed,using the calculation algorithm of missile’s attitude angle based on quaternion,using the beam scanning stable algorithm of phased array radar seeker to compensate for the beam scanning errors,achieving the purpose of seeker’strap-down,and simulating the algorithm of the quaternion and beam scanning stable in MATLAB,obtain a better decoupling effect,at last obtained the strap-down decoupling digital platform of phased array radar seeker has the characters such as simple in principle,little computation and high efficiency decoupling.
