This work studies the feasibility of using the joint multitarget particle filter to estimate the number of targets, and at the same time estimate the 5D target states including the positions, velocities and power levels.
Abstract
This work documents our investigation of multiple target tracking filters in proximity sensor networks when the target power levels are not known. The challenge is that when the targets are close, it is hard to determine if the sensor reports are the results of a loud target or multiple quiet targets. Given the binary measurements:1 for detection of targets and 0 for nondetection of targets, the works studies the feasibility of using the joint multitarget particle filter to estimate the number of targets, and at the same time estimate the 5D target states including the positions, velocities and power levels.

Multitarget Bayes filtering via first-order multitarget moments

TL;DR: Recursion Bayes filter equations for the probability hypothesis density are derived that account for multiple sensors, nonconstant probability of detection, Poisson false alarms, and appearance, spawning, and disappearance of targets and it is shown that the PHD is a best-fit approximation of the multitarget posterior in an information-theoretic sense.

Multitarget tracking using the joint multitarget probability density

TL;DR: This work addresses the problem of tracking multiple moving targets by recursively estimating the joint multitarget probability density (JMPD) and gives an implementation of the JMPD method based on particle filtering techniques and provides an adaptive sampling scheme which explicitly models the multitarget nature of the problem.

Target Tracking by Particle Filtering in Binary Sensor Networks

TL;DR: The proposed particle filtering algorithms for tracking a single target using data from binary sensors are extended to include estimation of constant parameters, and the posterior Cramer-Rao bounds (PCRBs) for the states are derived.

Target tracking with binary proximity sensors

TL;DR: Using geometric and probabilistic analysis of an idealized model, it is proved that the achievable spatial resolution in localizing a target's trajectory is of the order of 1/ρR, where R is the sensing radius andπ is the sensor density per unit area.

Bayesian optimization algorithm, decision graphs, and Occam's razor

TL;DR: The use of decision graphs in Bayesian networks to improve the performance of the BOA is proposed and a complexity measure is incorporated into the Bayesian-Dirichlet metric forBayesian networks with decision graphs.
