Abstract :
In this paper we investigate the tracking and detection of moving radioactive sources using an array of sensors that are deployed along the highway to collect gamma particle counts. When a potential radioactive source carrier passes by the array of sensors, gamma particle counts are collected and are sent to a fusion center for estimating vehicle motion state using particle filter technique. Then the radioactive sources detection is carried out using likelihood ratio test scheme. The performance of tracking and detection test scheme is shown by the numerical result.
