【Abstract】 Data association is an important step in ambiguity resolution in multiple target environment. In this paper, we analyse some kinds of targets that may occur and the reasons when there is no false alarm and no detector loss(no blind area). And we present a condition of measurements that of same targets and a method of data association, and point out some cases that false targets cannot be removed.更多还原
