Bayesian multitarget tracker for multistatic sonobuoy systems

Abstract

The paper presents the latest stage in the development of a robust multitarget tracker to be deployed in a large multistatic sonobuoy system. The major technical challenges are: the association of multiple measurements from different receivers for every ping; target detection dependence on the source-target-receiver geometry, ping properties, target properties and acoustic propagation conditions; and the combination of different measurement modalities (with and without the Doppler). The tracker is formulated as the multi-sensor linear-multitarget Bernoulli filter and, due to the highly nonlinear measurements, implemented using the sequential Monte Carlo method. The amplitude of detections is..
