引信与导引头一体化设计是提高引战配合效率的有效途径。基于改进后的去偏转换测量自适应卡尔曼滤波算法,把定向战斗部中心破片飞向角与弹目视线角之差作为起爆控制量,实现了一体化引信“全公式”化定向起爆控制。该算法将球坐标系中的测量信息转换到直角坐标系下,消除偏差后进行自适应滤波。利用前两点测量值,建立了滤波初始状态。仿真结果表明,该滤波算法参数估计精度很高,能提高引战配合效率。

The coordinated efficiency of fuze and warhead can be improved by integrated design of fuze and seeker. Based on converted measurement adaptive Kalman filtering algorithm with debasing, integrated fuze makes warhead dispersion-oriented come true by regarding the difference between the angle of antenna beam and dispersion directional angle of center fragment as controlled variable of fuze action. In this algorithm, the measured value of seeker initially set in polar coordinate system is converted to that reset in rectangle coordinate system and debased. The initial estimation of filtering is established by the first and second measurement. The results of simulation indicate variables can be estimated very well and the coordinated efficiency of fuze and warhead is improved.
