摘　　要：提出了一种基于锚系垂直阵列的对水下移动目标警戒的方法,论述了基于锚系垂直阵列时频瞬态特性探测和空间相关性探测的原理。利用海洋环境与目标噪声在时-频域与空间上的差异,对水下移动目标探测警戒,探测概率高且计算相对简便。垂直阵列悬挂于锚系潜标的系留缆或直接作为潜标的系留缆,布放机动灵活、适应水深范围广,可用于对水下移动目标的长周期、定点、大范围实时监测。This paper puts forward an alert method for underwater mobile target based on moored vertical array,and discusses its theories of time-frequency transient characteristics detection and spatial correlation detection. The underwater mobile vehicle is monitored by utilizing the time-frequency and spatial difference between ocean environment and target noise,and this method has high detection probability with simple calculations. The vertical arrays are hanged on mooring cables of moored submerged buoy or directly used as mooring cables,and they can be used for long period and wide range fix-point real-rime monitor for underwater mobile target,because of its good tactical performance and adaptation to wide-range water depth.
