A Spatiotemporal Alignment Method for Localization with MIMO Antenna Arrays Integration

Accurate spatiotemporal alignment is crucial for multi-sensor fusion in Localization scenarios. Significant temporal discrepancies between sensors can affect alignment quality, particularly in systems employing Multiple-Input Multiple-Output (MIMO) antenna arrays. In this study, we propose a novel method based on information trajectory segments for real-time spatiotemporal alignment estimation. Experimental results demonstrate that our approach consistently enhances localization accuracy across various temporal offsets. This method proves robust against time discrepancies, improving the reliability of localization systems integrated with MIMO antenna arrays.
