Abstract
According to the problem of ambiguous location and non-solution caused by system error and accidental error in the passive TDOA position system,a method of adding a receiving station has been adopted to locate target based on the study to the four-station location system which the pseudo-inveree method is adopted as the solving method and the fart that different station distribution have different results.Five stations are chosen and grouped by the main station cycle to get the measurement set of results with the target TO A of the five receiving stations.Correlation analysis and ambiguity value rejection to the measurement has been done.The final target location information has got by fusion process with less than five correct values.It is verified by simulation experiment which shows that the method can solve the problem of non-solution and ambiguous location with four stations and improve the positioning accuracy and is very suited for engineering on real data with random error.关键词
