Abstract
The "background-agnostic" CPHD filter was introduced at the 2010 SPIE Defense, Security and Sensing Symposium in 2010. It is a CPHD filter that is capable of operation when both the clutter background and the target-detection profile are unknown and dynamically changing. These CPHD filters are also capable of on-the-fly estimation of the intensity function and cardinality distribution of the clutter process. Leveraging ideas of Ristic, Clark, and Vo, this paper describes a generalization of the background-agnostic CPHD filter that can also estimate the intensity function and cardinality distribution of the target-appearance process. The probability distributions of the clutter and target-birth processes can also be estimated. © 2014 SPIE.
