Research on the detection probability of multi-band optical detection system

Abstract

Different operation models of joint optical multi-band detection systems are provided here, corresponding to the different characters of detecting probabilities of subsystems. It leads to a higher over-all detecting probability. The joint optical detection system is able to be operated under different models when detection probabilities of subsystems are low or there is big difference among the probabilities. When all the probabilities of subsystems are low, the joint optical detection system directly conducts data fusing. If there is big difference among the probabilities of subsystems, information from the subsystems is chosen before entering the fusion center. In this way, the false-alarm probability of the joint optical detection system reduces obviously comparing with direct data fusion. So it also can reduce the calculation of system and improve the competence of system.
