ON THE “SPOOKY ACTION AT A DISTANCE” IN THE CPHD FILTER

Öz Using the pair correlation function, spooky interaction between distant targets in the cardinalized probability hypothesis density (CPHD) filter is investigated. It is shown that the spooky interaction between distant targets in the CPHD filter is a direct result of its independent identically distributed cluster process (IIDCP) target model. That is, the spooky effect in the CPHD filter is not due to the indistinguishable nature of the elements in the unlabeled random finite set formulation, but due to the particular approximation of target process assumed by the CPHD filter
