1. A method for updating a target track, the method comprising: receiving a measurement associated with a target track at a first sensor node; estimating a local posterior density based on the received measurement at the first sensor node; receiving parameterized data from a second sensor at the first sensor node; receiving third parameterized data from a third sensor at the first sensor node; reconstructing a second local posterior density by a processor at the first sensor node based on the received parameterized data; reconstructing a third local posterior density by the processor at the first sensor node based on the received third parameterized data; estimating a global posterior density using the estimated local posterior density the reconstructed second local posterior density at the first sensor node, and the reconstructed third local posterior density; updating the target track using the estimated global posterior density by the processor at the first sensor node.
