| 摘 要： | 超短基线定位系统在海洋开发中具有广泛的应用,与其它基线相比,基阵尺寸小,易于安装。由于在远距离误差发散快,超短基线作用距离不远,其远距离定位精度也不高。为了满足深海作业需要,需要研制高精度长程超短基线定位系统,论述了系统的组成及设计,并通过改进基阵阵形、降低接收机噪声等方面提高系统定位精度。

| Abstract: | Ultra-Short BaseLine system(USBL) is used widely in ocean exploiture.This technique is more convenient than other baseline in that its aperture size is small and it is easy to install.However,the USBL has lower accuracy in long range operation.In order to meet the need of deep-water application,it's required to develop high accuracy long range ultra-short baseline system.This paper discusses the design of system and the positioning precision is improved by changing the array's form and decreasing the noise of receiver. |

| Keywords: | USBL design of system positioning precision |
