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. -
