Intelligence-Aware Batch Processing for TMA with Bearings-Only Measurements
Sensors, 2021 This paper develops a framework to track the trajectory of a target in 2D by considering a moving ownship able to measure bearing measurements. Notably, the framework allows one to incorporate additional information (e.g., obtained via intelligence) such

Gaussian‐like measurement likelihood based particle filter for extended target tracking
IET Radar, Sonar & Navigation, 2023 Extended target tracking based on the star‐convex model is a multi‐dimensional nonlinear estimation problem. To approximate the shape of an extended target, the star‐convex model requires a higher‐order Fourier series expansion, which will increase the ...

SICE Journal of Control, Measurement, and System Integration, 2020 This paper proposes a recursive elimination method for optimal filtering problems of a class of discrete-time nonlinear systems with non-Gaussian noise. By this method, most of the computations to solve an optimal filtering problem can be carried out off-

TMA from Cosines of Conical Angles Acquired by a Towed Array
Sensors, 2021 This paper deals with the estimation of the trajectory of a target in constant velocity motion at an unknown constant depth, from measurements of conical angles supplied by a linear array. Sound emitted by the target does not necessarily navigate along a
