利用多普勒信息的多途被动定位方法

A multipath passive location algorithm using Doppler information

本文提出一种利用目标辐射噪声多普勒信息的多途被动定位方法，推导了该方法的参数估计方差下限。对海上实录的一条鱼雷辐射噪声信号进行了处理，给出了鱼雷深度、速度、运动轨迹的估计值，结果与实际相符，证明了算法的有效性。

A multipath passive location algorithm is presented here using Doppler Shift information of the radiated noise of target. The lower bound of the varience of parameter estimation is derived. The radiated noise of a torpedo recorded in the field of sea is processed and the depth, speed and moving trace of this torpedo are estimated. The experimental results indicated that the algorithm is effective.
