Bearing-only Tracking using Towed Sensor-Array with Non-Gaussian Measurement Noise Statistics
Rohit Kumar Singh, Subrata Kumar, Shovan Bhaumik
Passive bearing-only tracking (BOT) estimates the target states by utilising noisy bearing measurements captured by a sensor array. The sensor array is often towed behind the ship,…
Gaussian Integral based Bayesian Smoother
Rohit Kumar Singh, Kundan Kumar, Shovan Bhaumik
This work introduces the Gaussian integration to address a smoothing problem of a nonlinear stochastic state space model. The probability densities of states at each time instant a…
Dynamics of a Towed Cable with Sensor-Array for Underwater Target Motion Analysis
Rohit Kumar Singh, Subrata Kumar, Shovan Bhaumik
During a war situation, many times an underwater target motion analysis (TMA) is performed using bearing-only measurements, obtained from a sensor array, which is towed by an own-s…
Maximum Correntropy Polynomial Chaos Kalman Filter for Underwater Navigation
Rohit Kumar Singh, Joydeb Saha, Shovan Bhaumik
This paper develops an underwater navigation solution that utilizes a strapdown inertial navigation system (SINS) and fuses a set of auxiliary sensors such as an acoustic positioni…
