摘　　要：水中目标定位技术为人们在海洋上进行的各种活动提供方位信息。在机器工作状态检测、某些兵器应用中,有时并不要求精确的噪声源或目标定向,而只要求能检测出固定的区域范围,对其进行有效打击。因此,在进行目标检测的同时实现其动作区域控制,具有广泛的工程实践应用价值。基于此,主要研究互谱算法的原理,通过相位差计算目标距离信息,建立检测动作区域控制模型,通过建立检测区域及定位模型,推导出算法并进行Matlab软件分析验证算法的可靠性。Underwater target location technology provides orientation information for people to carry out various activities on the ocean.In machine working state detection and some weapons application,sometimes it is not required to be precise noise source or target orientation,but only to be able to detect a fixed area range for effective attack.Therefore,it has a wide range of engineering practical application value to realize the control of motion area while carrying out target detection.This paper mainly studies the principle of cross-spectrum algorithm,which calculates the target distance information by phase difference.The control model of the detection action region was established.The algorithm was deduces by establishing the detection region and positioning model,and the reliability of the algorithm was verified by Matlab software analysis.
