对运动目标螺旋搜索模式分析

对运动目标搜索是军事系统工程的ー个重要内容,其在很多领域具有广泛应用，如对潜艇搜索、对失事舰船飞机搜救、制导武器捜索捕捉目标等。用运动学和数学的有关知识分析了目标定速直航运动时的分布函数以及搜索者与目标可相遇的条件，提出了对运动目标按螺旋线搜索的另ー种证明方法，建立了直线搜索时目标可能位置点的数学模型，并以此为依据分析了对运动目标螺旋搜索模式的ー个误区。

Analysis on Spiral Search Pattern for Moving Target

Searching for moving targets is an important content of military system engineering, which can be used in many areas, such as searches for submarines, wrecked airplanes or warships and targets by guided weapons. The distribution function and the meeting condition of searchers with moving targets were analyzed by relative knowledge of kinematics and mathematics at constant velocity and straight line. Another proving method about search for moving targets according to spiral line was put forward, and the mathematics model of target probable position was set up as searching for targets along straight line. From this model, it can be proved that there is a wrong thought about search for moving targets according to spiral line.
