Abstract
A method for providing assurance of data association comprises formulating a track permutation matrix of measurement statistics based on sensor measurement returns; receiving a first set of correlated tracks from a correlator module (set a), identified as originating from a target; selecting a second set of correlated tracks from the track permutation matrix (set b), based on branching and bounding techniques; reframing verification of a data association framework into a linear inequality, with a first portion of the linear inequality based on set a, and a second portion of the linear inequality based on set b; and performing a formal methods-based verification procedure to determine whether properties of set a are bounded by properties of set b. If properties of the correlated tracks within set a are bounded by, or are less than or equal to, properties of the correlated tracks within set b, then the correlated tracks are verified.
