| Abstract: | 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. |
