反舰导弹对沿岸航行目标捕捉算法研究

Research on Anti-ship Missile Acquire Target Sailing along Coast

针对寻的雷达不能从海岸背景中自动识别目标情况的问题,根据反舰导弹的工作原理和海岸的特点,建立了反舰导弹寻的末制导雷达搜索区界模型、简化的海岸模型,进而建立了基于目标位置、海岸与寻的雷达搜索区交点的动态捕捉模型,并得到反舰导弹对沿岸航行目标的捕捉判定方法。仿真结果表明,该模型能较准确的反映目标离岸距离、目标速度、导弹自导距离和进入目标角度对目标捕捉概率的影响。

In order to solve the problem that homing radar can not identify target automatically in the background of coast,models of homing radar’s searching zone and simplified coastline were built,which is based on working principles of anti-ship missile and characteristics of the coast. Then,a select principle based dynamic acquire model was built on target position,intersection points of coast and search-zone of homing radar. Simulation shows that model can accurately calculate the influence of target-coast distance,target speed,auto-guided range,missile’s enter angle and select principle on acquire probability,which has a practical value.
