基于Page Test的主动声呐检测接触提取

Extracting detection contacts of active sonar using the page test

引入一种序贯检测算法—Page Test算法,应用到主动声呐目标自动检测中,获得目标信号的起始时间和结束时间,再利用分裂波束法获得相位差信息,将二者结合,得到方位、距离精度较高的检测输出。仿真和实验数据处理表明,该算法可以提供方位、距离精度较高的接触点,具有较好的应用效果。对于获得的检测接触可用于多Ping显示及声呐目标自动跟踪。

This paper studied a sequential test algorithm called the Page test algorithm. In the active sonar detection,we use it to acquire the leading edge and lagging edge of a signal. We proposed to combine the phase information of split beam forming with the page test to make detection contacts. The result of simulation and experiment data process showed that the method can improve the bearing accuracy and distance accuracy effectively. The detection contacts could be used for multi-ping display and sonar automatic track.
