second-generation PHD_CPHD filters and multitarget calculus

The “classical” PHD and CPHD filters presume the standard “small-target” detection model. This year, in a series of theoretical studies, I have derived new “second-generation” CPHD/PHD filters for various sensing conditions that cannot be described by the standard model. These are: (a) multisensor, (b) clutter estimation, (c) tracking in unknown clutter, (d) extended targets, (e) unresolved targets, and (f) superpositional sensors. A common factor underlies all of these derivations: the FISST mult
