Methods and apparatus utilizing digital signal processing of ultra wide band radar signals for living object detection in wireless power transfer applications

This invention describes a safety system for wireless power transfer, particularly for detecting living objects. It uses ultra-wideband radar to scan the area where power is being transferred. A processor receives these radar signals, converts them to digital, filters out background noise and constant signals, and then processes them to determine if an object is present, its distance, speed, and direction.

Why it matters: Since 2015, the cost and availability of compact UWB radar modules have significantly improved. Advancements in embedded processing power and real-time DSP algorithms also make implementing such a system more feasible and efficient today.

Status: Not in forceListed as no longer active. The specific reason is not in the record we hold.
How hard to build: SpecializedUWB radar hardware, complex DSP algorithms
