Ultrawide-Band Object Localization with Line-of-Sight Signal Classification

The patent segments the received signal into multiple components using signal decomposition techniques, separating the direct line-of-sight signal from reflected multipath signals. This allows the system to selectively process only the direct signal components for localization calculations, thereby maintaining high accuracy while still utilizing signals that have propagated through various paths to achieve broader coverage.

The patent introduces an intermediary signal processing layer that acts as a mediator between the received radio signals and the localization algorithm. This intermediary layer performs signal classification, decomposition, and selection operations to identify and extract direct line-of-sight signal components from the mixed signal environment, enabling accurate localization even when signals traverse complex propagation paths.

The patent performs preliminary signal classification and decomposition operations before the main localization calculation. By pre-processing the signals to identify and separate direct signal components from multipath reflections, the system prepares clean, classified signal data that can be directly fed into standard localization algorithms, thereby achieving high accuracy without significantly increasing the complexity of the core positioning function.

The patent replaces complex mechanical or geometric signal filtering methods with signal processing-based classification techniques. Instead of using physical antenna arrangements or geometric constraints to separate direct and reflected signals, the system uses computational methods to analyze signal characteristics and classify components, achieving accurate separation with simpler hardware configurations.
