State Estimation from Range-Only Measurements

2020

In this paper, a method of state estimation from range-only measurements is presented. This makes it possible to use low-cost sensor networks which cannot provide accurate azimuth information to replace large antennas for target tracking …

Multiframe weak target track-before-detect based on pseudo-spectrum in mixed coordinates

2021 · Chinese Journal of Aeronautics

Traditional multiframe Track-Before-Detect (TBD) may incur adverse integration loss resulting from model mismatch in sensor coordinates. Its suboptimal integration strategy may cause target envelope degradation. To address these issues, a pseudo-spectrum-based multiframe TBD in mixed …

A Switch-Constrained Multiple Model Smoothing Algorithm for Maneuvering Target Tracking

2024

In most existing multiple model (MM) smoothing algorithms for maneuvering target tracking, the mode evolution process is usually described by a Markov chain, which implicitly assumes that the target mode may switch at all time …
