Several results of dempster - shafer ( d - s ) method applied to target fusion identification of two sensors and conclusions drawn from them were given and proved . the recurrence formula of multi - sensor ( > 2 ) d - s fusion identification were derived and their properties were shown clearly 并针对多传感器的目标识别问题,文中给出并证明了两个传感器dempster - shafer ( d - s )融合识别同一目标时的若干结论及其归纳的结论,同时推出了多( 2 )传感器dempster - shafer融合识别同一目标时的递推式,并分析了它们的性质。
