摘　　要：研究了目标脱靶方位识别原理,分析了定向战斗部破片动态飞散区的散布特性。把定向战斗部中心破片飞向角与引信波束指向角之差作为起爆控制量,提出了一种二维波控引信与定向战斗部配合的方法。在引制信息一体化条件下,研究了一种改进自适应卡尔曼滤波算法在此引战配合中的应用。该滤波算法将球坐标系中的测量信息转换到直角坐标系下进行滤波,并消除了偏差。利用前两点比较精确的测量值,建立了滤波初始状态。仿真结果表明,应用该滤波算法能得到很高的参数估计精度,能满足引战配合的需要。The principle of target miss identification in azimuth and the dispersion area of warhead fragment were studied. A new method was presented which used two-dimensional beam controlled fuze coordinated with orientation warhead, taking the difference between the angle of antenna beam and dispersion directional angle of center fragment as the initiation control parameter. The application of an improved self-adapting Kalman filtering in the fuze/warhead coordination was studied based on GIF （ Guidance Integrated Fuze） technology. In this algorithm, the measured value of seeker initially set in polar coordinate system was converted into the rectangular coordinate system for filtering, and the bias was eliminated. The initial estimation of filtering was then established by using the first and second measurements. Results of simulation indicated that high estimation precision can be obtained by using this filtering algorithm, which can satisfy the coordination of fuze and warhead proposed here.
