BEACON AND ASSOCIATED COMPONENTS FOR A RANGING SYSTEM

摘要

A beacon (110) for a ranging system includes an electronic scanned array (ESA) antenna and a transceiver. The ESA antenna is configured to emit a separate radio frequency (RF) phased-array narrow beam (140) for each of a plurality of segments of an arc, and receive from an end user node (130) a response signal based on at least one of the RF phased-array narrow beam (140). Each segment of the arc is scanned at a specified time interval. The transceiver is configured to transmit a pulsed signal via the RF phased-array narrow beam (140), and receive the response signal.
