Integrating Design of Millimeter Wave and Infrared Dual-mode Imaging Seeker and Fuze

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。基于毫米波与红外双模复合探测的优点,将其与波控引信结合进行引制一体化设计,介绍了一种毫米波与红外双模复合引制一体化设计的算法流程,分析了弹目交会模型中影响最佳起爆角的因素,推导了起爆延时的数学表达式,最后分析对比了α-β(GH)滤波和α-β-γ(GHK)滤波算法对最佳起爆角和起爆延时的估计效果。仿真结果表明,GH滤波在大交会角低速交会效果较好,GHK滤波在小交会角高速交会效果较好,且两种滤波时效性强,计算精确,能够为引制一体化预测算法提供可靠数据。

The coordinated efficiency of fuze and warhead can be improved by integrated design of fuze and seeker. On the basis of the merits of the millimeter wave and infrared dual-mode compound detection, one design of Guidance Integrated Fuzing （GIF） is proposed integrating with wave-control fuze. The algorithm flow of the GIF is stated together with the corresponding meeting model. The impact factors of the optimum detonating angle are analyzed together with expression of detonating time-lapse. Finally, the estimated optimum detonating angle and detonating time-lapse respectively based on a-β（GH） and a-β-y（GHK） filter are contrasted. The simulation results validate the efficiency and applicability of the mentioned two filters. The GH filter suits the missile-target encounter model with low speed and big encounter angle, while GHK filter suits the model with high speed and small encounter angle. The filtered data are precise and are able to provide reliable data for the predicted algorithm of the GIF.
