对运动目标螺旋搜索误区分析

Analysis on Spiral Search Missed Area Pattern for Moving Target

对运动目标搜索是军事系统工程的一个重要内容,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、制导武器搜索捕捉目标等。用运动学和数学的有关知识分析了目标定速直航机动时的分布函数以及搜索者与其可相遇的条件,提出了对运动目标按螺旋线搜索的另一种证明方法,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一个误区。

Searching for moving target is an important content of military system engineering,which can be used in many areas ,such as searching for submarine and wreck airplane or warship and searching for target by guided weapon and so forth. In this paper,the author analyzes the distribution function and the meeting condition of searcher with moving target according to knowledge of moving research and mathematics when target moves at constant velocity and in straight line, and puts forward another proving method about searching for moving target according to spiral line, and set up the mathematics model of target＇s probable position as searching for target along straight line. According to this model, it can be proved that there is a wrong thought about search for moving target according to spiral line.
