中文摘要:
      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.
英文摘要:
      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.
