摘要: 本文提出了多傳感器檢測區(qū)域的劃分,以及先分區(qū)融合再系統(tǒng)融合的方法,并且在不同的檢測區(qū)域,傳感器采用不同的門限。給出了該方法的虛警概率和檢測概率表達(dá)式,并介紹了它在分布式CFAR檢測系統(tǒng)中的應(yīng)用。結(jié)果表明,通過設(shè)置不同的門限,可以提高系統(tǒng)的檢測概率。

Abstract: The multisensor detection area partitioning is considered. An approach is presented to the fusion in each detection area where the sensor uses different thresholds and then at system level. The expressions of the detection probability and false alarm probability are given. An apph cation of the method is illustrated to distributed CFAR detection systems. The results show that the system detection probability may be improved by setting different thresholds for a detector. -
