Access Track-before-detect procedures for detection of extended object Ling Fan * , Xiaoling Zhang and Jun Shi Abstract In this article, we present a particle filter (PF)-based track-before-detect ... SNR is low, the more the detection delay is serious. For example, the target present is declared immediately at k = 6 for SNR = 12 dB, but for SNR = 3 the target present is declared till...
