摘　　要：针对深海条件下的动态目标检测,研制了一套分布式浮标阵自主定位的数据获取系统.系统主要由GPS接收机、数据控制中心、浮标阵组成.在测试环境中,布置4个定位浮标和若干测试浮标,分别获取定位信标信号和测试数据.GPS授时实现各浮标的时间同步;数据控制中心负责对浮标阵的控制管理,对接收到的各浮标数据进行处理和分析.实验表明,该系统的时间同步精度达到微秒级,定位精度在50 cm.In order to detect the dynamic target in the ocean, a data acquisition system based on self- positioning of distributed buoy array was studied, which consisted of a GPS receiver, a data control center and a distributed buoy array. There were 4 positioning buoys and several testing buoys in the test environment for acquiring the location beacon signals and test data. GPS controlled time signals to achieve synchronization for all buoys. The data control center controlled the buoys, processed and analyzed the data received from buoys. The experiment shows that time synchronization accuracy is at microsecond level and positioning accuracy is within 50 cm for the system.
