Abstract
The probability hypothesis density (PHD) filter is a first moment approximation
to the evolution of a dynamic point process which can be used to approximate
the optimal filtering equations of the multipleobject tracking problem.
We show that, under reasonable assumptions, a sequential Monte Carlo (SMC) approximation
of the PHD filter converges in mean of order p ≥ 1, and hence almost
surely, to the true PHD filter. We also present a central limit theorem for the SMC
approximation, show that the variance is finite under similar assumptions and establish
a recursion for the asymptotic variance. This provides a theoretical justification for this implementation of a tractable multipleobject filtering methodology
and generalises some results from sequential Monte Carlo theory.
