Evidence Consistent with the Multiple-Bearings Hypothesis from Human Virtual Landmark-Based Navigation [PDF]

Frontiers in Psychology, 2015
One approach to explaining the conditions under which additional landmarks will be learned or ignored relates to the nature of the information provided by the landmarks (i.e., distance versus bearings). In the current experiment, we tested the ability of

A New Coarse Gating Strategy Driven Multidimensional Assignment for Two-Stage MHT of Bearings-Only Multisensor-Multitarget Tracking

Sensors, 2022
The problem of two-dimensional bearings-only multisensor-multitarget tracking is addressed in this work. For this type of target tracking problem, the multidimensional assignment (MDA) is crucial for identifying measurements originating from the same ...

Way-Finding and Landmarks: The Multiple-Bearings Hypothesis

Journal of Experimental Biology, 2001
ABSTRACT Clark’s nutcrackers (Nucifraga columbiana) are capable of very precise searching using the metric relationships between a goal and multiple landmarks to relocate the goal location. They can judge the direction more accurately than the distance to a landmark when the landmark is distant from the goal.

Improved Multitarget Tracking in Clutter Using Bearings-Only Measurements

Sensors, 2018
Multitarget tracking in clutter using bearings-only measurements is a challenging problem. In this paper, a performance improved nonlinear filter is proposed on the basis of the Random Finite Set (RFS) theory and is named as Gaussian mixture measurements-

Improved Maneuver Detection-Based Multiple Hypothesis Bearing-Only Target Tracking Algorithm

Electronics
In ground-based bearing-only tracking of multiple maneuvering targets, there are difficulties in data association due to the reliance solely on azimuth information, making it challenging to distinguish and identify multiple targets. This problem is particularly pronounced when targets are close or overlapping, leading to disassociation or target loss ...
