Paper Abstract

SUppose that a multitarget tracker is used to track a dim target in heavy clutter. In the paper 'Characteristics of the Acquisition of a Dim Target in Clutter', Oliver Drummond has pointed out that, for such a tracker, target acquisition is a very different problem than target detection. In particular, target acquisition requires two Receiver Operating Characteristic (ROC) curves; whereas target detection requires only one. In past presentations at this and other conferences and in the book Mathematics of Data Fusion, we have introduced 'finite-set statistics' (FISST), a direct generalization of conventional single-sensor, single-target statistics to the multitarget realm. In this paper we show how FISST results in a unification of both detection and acquisition under a familiar decision- theoretic framework. The basic idea is to use a unified Bayesian single-target tracker with clutter models, rather than a multitarget tracker. In analogy to a conventional detection problem, the acquisition problem is reduced to a conventional decision problem. In particular, we show how to define an 'acquisition ROC curve' for this sort of generalized detection problem.
