烟幕弹对毫米波末制导雷达的有效遮蔽区域研究

Research of Effectively Obscuring Region Posed by Smoke Screen for Millimeter-wave Terminal Guided Radar

为形象表达烟幕弹的威力范围,提出了烟幕有效遮蔽区域的概念,通过计算烟幕弹的烟幕面密度、烟幕弹对毫米波末制导雷达的遮蔽面密度,得到烟幕弹对毫米波末制导雷达有效遮蔽区域的计算模型,通过实例仿真后,分析了不同条件下有效遮蔽区域的变化规律,从而得到单发烟幕弹的最大遮蔽方向在目标与烟幕弹连线方向等一系列结论,同时验证了用有效遮蔽区域表示烟幕弹威力范围的正确性。

In order to embody effective range of smoke bomb, the concept of effectively obscuring region （EOR）of smoke-screen was pro- posed, and the calculation model of the EOR posed by smoke screen for millimeter-wave terminal guided radar（MMWTGR） was present by means of calculation of smoke surface density and obscured surface density of MMWTGR posed by smoke bomb. The VC ＋ ＋ simulation was used to analyze changing rule of the EWR under different conditions so as to obtain some useful characteristics of smoke bomb obscu- ring. Several conclusions have been reached, for example, the maximum obscuring direction of the smoke-screen is the direction of the line from target to the smoke bomb. At the same time, correctness of expressing effective range of smoke bomb by EOR was verified.
