A system is provided with a ranging transmitter and receiver pair or a transceiver pair. The system classifies a group of radio frequency (RF) channels between ranging transmitter and receiver pairs. In a first scenario, a ranging transmitter transmits at least three channels to an active reflecting receiver. A ranging receiver then receives reflected instances of the at least three transmitted channels from the active reflecting receiver. A processor of the system then determines a ranging measurement between the ranging transmitter and the active reflecting receiver based on measured phase changes and received signal strength and assigns a classification to the determined ranging measurement indicating a relative level of accuracy for the determined ranging measurement. The classification may be a general classification, a linearity classification, a multipath classification, or a combination classification that is based on both a linearity classification and a multipath classification.

Measurement accuracy classifier for high-resolution ranging

Systems and methods for providing personal radar, object presence detection, and object localization are provided. Multiple devices that perform high-resolution ranging can be operated to perform radar in an area, detect objects and motion of objects in the area, and generate a virtual steerable antenna.
