Abstract
The notion of indistinguishable targets is wellestablished in advanced target tracking. Conceptually, it is rooted in quantum physics where functions of joint particle states are considered that are either symmetric or antisymmetric under permutation of the particle labels. This symmetry dichotomy explains why two disjunct classes of particles exist in nature: bosons and fermions. Besides symmetry, also antisymmetry has a place in multiple target tracking as we will show, leading to welldefined probability density functions describing the joint target states. Inbuilt antisymmetry implies a target tracking version of Pauli'sexclusion principle: Real world targets are “fermions” that cannot exist at the same time at the same place. This is of interest in dense tracking scenarios with resolution conflicts and splitoff. We discuss the concept and illustrate its benefits.
