基于地形梯度法的巡航导弹来袭方向判断

在满足地空导弹部队战术需求的条件下,为了提高巡航导弹来袭方向判断的速度,建立了地形梯度预测模型。该模型将地空导弹威胁源和高炮威胁源统一等效为含等高线的威胁源地形,并将此类地形与实际地形叠加生成战场环境地形。把此地形均匀划分为8个方向,分别计算每个方向内综合威胁指数最小且满足巡航导弹进袭梯度要求的连续梯度带面积除以该方向总面积。通过比较面积比计算出巡航导弹的最大可能来袭方向。经过模拟仿真证明该模型具有算法简单、速度快和可操作性强等优点,同时也能充分发挥指挥员在来袭方向判断中的主观能动作用,为快速定下战斗部署决心和提高巡航导弹拦截概率提供支持。

Estimating the cruise missile's attacking direction based on terrain grads

In order to improve the estimating speed of CM'S attacking direction under the restriction of surface-to-air missile unit's tactics requirements,we set up a terrain grads model to estimate the intruding direction.This model traits the threaten source of SAM and Archibald as threaten-terrain,pile it up into real landform to make up battlefield-terrain.And then divide this terrain into 8 directions,by calculating the ratio of two acreages can get the mostly attacking direction of CM.According to the simulation result,this model proves to be simple/rapid and manipulate,at the same time it can exert the commander's subjective motile during the estimating process.And all of these not only could provide great support to make quick battle disposition decision but also improve the anti-CM'S probability.
