基于卡尔曼滤波的水下融合定位算法仿真

Under water fusion location algorithm used in Kalman filter

本文仿真了基于卡尔曼滤波的水下多个水听器定位算法,首先采用接收信号强度指示器(RSSI)将每个水听器接收到的信号转化为水听器与目标的距离,多个水听器距离值通过卡尔曼滤波融合,得到目标实际方位。算法仿真中用最小二乘法进行定位精度对比分析。

the location algorithm based on Kalman Filter used many hydrophones is discussed in this paper.First,received signal strength indicator is used to convert received signals to distance between hydrophone and target,many distances are fusioned by Kalman Filter to get the real direcation of the target.
