Abstract:

In view of the failure of almost all the methods of the multiple stations passive location in the uncommon-view,this paper propose a new method using only the time of arrival (TOA) in this situation.The TOA train of every net point is produced and the one that is most like of the real train is the excellent.Then the paper analyzes how the components affect the location precision such as the TOA-error,the distribution of the stations,the distances between the substations and the main-station and the observation time.The results of the emulation prove that a precision close to the CRLB lower limit can be achieved without considering the error of the station address and the clock synchronization.

Key words: uncommon view;TOA process;passive location
