Trigonometric Moments of a Generalized von Mises Distribution in 2-D Range-Only Tracking
Nikhil Sharma, Shovan Bhaumik, Ratnasingham Tharmarasa +1
A 2D range-only tracking scenario is non-trivial due to two main reasons. First, when the states to be estimated are in Cartesian coordinates, the uncertainty region is multi-modal…
Tracking an Underwater Target with Unknown Measurement Noise Statistics Using Variational Bayesian Filters
Shreya Das, Kundan Kumar, Shovan Bhaumik
This paper considers a bearings-only tracking problem using noisy measurements of unknown noise statistics from a passive sensor. It is assumed that the process and measurement noi…
Risk Sensitive Filtering with Randomly Delayed Measurements
Ranjeet Kumar Tiwari, Shovan Bhaumik
Conventional Bayesian estimation requires an accurate stochastic model of a system. However, this requirement is not always met in many practical cases where the system is not comp…
Modeling and Estimation for Systems with Randomly Delayed Measurements and Packet Dropouts
Ranjeet Kumar Tiwari, Shovan Bhaumik
A networked system often uses a shared communication network to transmit the measurements to a remotely located estimation center. Due to the limited bandwidth of the channel, a de…
Robust Maximum Correntropy Kalman Filter
Joydeb Saha, Shovan Bhaumik
The Kalman filter provides an optimal estimation for a linear system with Gaussian noise. However when the noises are non-Gaussian in nature, its performance deteriorates rapidly.…
Resolving Left-Right Ambiguity During Bearing Only Tracking of an Underwater Target Using Towed Array
Shreya Das, Ranjeet Kumar Tiwari, Shovan Bhaumik
In bearing only tracking using a towed array, the array can sense the bearing angle of the target but is unable to differentiate whether the target is on the left or the right side…
