An extended object in target tracking refers to the object which produces a time-varying number of noisy detections (measurements) from its scattering or feature points. The optimal sequential Bayesian state estimator for an appearing/disappearing extended object in the presence of false and missed…
Sonobuoy fields, comprising a network of transmitters and receivers, are commonly deployed to find and track underwater targets. For a given environment and sonobuoy field layout, the performance of such a field depends on the scheduling, that is, deciding which source should transmit, and which fro…
Sonobuoy fields, consisting of many distributed emitter and receiver sonar sensors on buoys, are used to seek and track underwater targets in a defined search area. A sensor scheduling algorithm is required in order to optimise tracking performance by selecting which emitter sonobuoy should transmit…
Rotational modulation collimation (RMC) is a technique commonly used for standoff imaging of radiological sources in the context of homeland security. The paper presents a novel method for gamma ray image reconstruction from modulation signals acquired by a RMC detector prototyped by DSTO. The image…
The paper is devoted to the implementation of the Sequential Monte Carlo Probability Hypothesis Density (SMC-PHD) filter. A measurement driven proposal for persistent target particles requires the predicted persistent target particles to be partitioned in a probabilistic manner using the received me…
