Method and system for determining object motion by capturing motion data via radio frequency phase and direction of arrival detection

摘要

Methods and systems for determining the motion of an object by capturing motion data. The methods and systems may comprise the use of motion sensor tags adapted for disposal on an object, wherein motion data may be collected by said motion sensor tags and transmitted via radio frequency signal for processing of collected data comprising the motion data, direction of arrival data, amplitude data, and phase data. The same system may also be adapted to determine the position of a UAV or aircraft by intercepting radio frequency communications signals emanating from the object.

1. A system comprising:
a plurality of motion sensor tags adapted to collect motion data from an object; at least one radio frequency transmitter adapted to transmit the motion data via a radio frequency signal; at least one phased antenna array adapted to receive the motion data from the radio frequency signal, and derive direction of arrival data, amplitude data, and phase data via receipt of the radio frequency signal; and at least one signal processor adapted to provide three-dimensional data comprising a position, an orientation, an acceleration, and/or a velocity of the object in a three-dimensional space by processing a collected data set comprising the motion data, the direction of arrival data, the amplitude data, and the phase data.
