基于时延差的声纳浮标阵定位仿真

被动方式的声纳浮标是应用于航空反潜中的一种重要设备,因为其隐蔽性好,效率高的特点备受关注。但是通常被动声纳浮标只能探测到目标方向,无法获知距离信息。论文提出了一种基于时延差得被动定位阵定位模型,介绍了定位算法,分析了定位误差,并通过插值法提高时延估计精度,进而提高定位精度,给出了仿真结果且进行了分析。

Simulation of Sonar-buoy Array Positioning System Based on Time Delay

Sonar-buoy working on passive location is a kind of very important equipment in antisubmarine. It absorbs atlention because of the advantage of concealment and effectiveness. But it only can find the direction of target and cannot get the distance information, A kind of passive location method based on time delay is shown in this paper. It presents the arith- metic and analyzes the error of location, improving the estimation precision as well as location precision by interpolation. Then this paper shows the simulation results and analysis.
