Passive Target Motion Analysis With Own‐Ship Location Uncertainty in the Presence of Non‐Gaussian Sensor Noise

IET Radar, Sonar &Navigation, Volume 19, Issue 1, January/December 2025.
This work explores underwater TMA by incorporating time delay and Doppler frequency measurements along with angle data, eliminating the need for own‐ship manoeuvre and improving estimation accuracy in presence of non‐Gaussian sensor noise. Furthermore, since the own‐ship's position is inherently uncertain due to navigation errors, this work addresses ...

Code Optimization for Strapdown Inertial Navigation System Algorithm [PDF]

, 2018
Inertial navigation systems are in common use for decades due to its advantages. Since INS outputs are usually used for inputs in different control algorithms (depending on applications), INS will induce certain errors and limitations. This chapter deals

SmokeNav: Millimeter‐Wave‐Radar/Inertial Measurement Unit Integrated Positioning and Semantic Mapping in Visually Degraded Environments for First Responders

Advanced Intelligent Systems, Volume 6, Issue 12, December 2024.
In this work, SmokeNav, a system that fuses inertial sensor and millimeter‐wave radar for accurate user localization and metric map reconstruction in visually degraded environments, is presented. Using a foot‐mounted inertial sensor with human motion constraints, SmokeNav leverages inertial positioning to construct occupancy maps from radar data.

Robust adaptive non‐linear alignment algorithm for SINS/DVL integrated navigation system based on variational Bayesian

IET Science, Measurement &Technology, Volume 18, Issue 9, Page 524-539, November 2024.
The proposed algorithm VBRAUKF is useful for dynamic alignment of SINS/DVL. According to the inaccurate modelling of the observation model, an adaptive estimation strategy for the measurement noise covariance is designed by Variational Bayesian algorithm based on unscented Kalman filter algorithm to solve dynamic attitude alignment for SINS/DVL ...
