舰载预警直升机搜索参数的优化设计

Optimization Design of Ship-Borne Warning Helicopters Search Parameters

舰载预警直升机在搜索目标的过程中需要确定载机搜索高度和机载雷达的波束俯仰角,依据机载雷达搜索原理,建立雷达载荷感知面积模型,结合作战约束确定符合要求的搜索参数。考虑机载雷达最大搜索距离和目标累积发现概率两个指标,建立机载雷达发现概率模型,在满足给定发现概率的情况下,得到对于来袭目标的最大探测距离,依据搜索参数优化设计舰载预警直升机的飞行高度和波束俯仰角范围,并给出了飞行高度与视轴俯角范围的使用与控制方法。

Ship-borne warning helicopter in the search target process needs to determine load machine search height and airborne radar beam angle of pitch.Based on airborne radar search principle, the establishment of radar load perception area model, arms constraint sure to meet the requirements of search parameters is combined. Considering the largest airborne radar search distance and target cumulative detection probability, airborne radar detection probability model is established to satisfy the detection probability given the circumstances,to get to the maximum detection range of an attack according to the search parameters the ship-borne warning helicopter flight height and beam angle of pitch range. And the flight altitude and optic axis dip Angle range of use and control method is giren.
