Phase difference of arrival geolocation

Mason, John J.; Romero, Louis (

Title: Phase difference of arrival geolocation

Abstract

Geolocation is performed by receiving, at a plurality of non-earthbound platforms each moving in a known manner within a spatial coordinate system, a radio frequency (RF) signal transmitted from a transmitter at an unknown location on earth within the spatial coordinate system. For each of the platforms, a phase change of the received frequency carrier is measured over the same duration of time. The measured phase changes are combined to determine the transmitter location.

Differential emitter geolocation

Patent Mason, John J.; Romero, Louis A.

An unknown location of a transmitter of interest is determined based on wireless signals transmitted by both the transmitter of interest and a reference transmitter positioned at a known location. The transmitted signals are received at a plurality of non-earthbound platforms each moving in a known manner, and phase measurements for each received signal are used to determine the unknown location.

Geospatial-temporal semantic graph representations of trajectories from remote sensing and geolocation data

Patent Perkins, David Nikolaus; Brost, Randolph; Ray, Lawrence P.

Various technologies for facilitating analysis of large remote sensing and geolocation datasets to identify features of interest are described herein. A search query can be submitted to a computing system that executes searches over a geospatial temporal semantic (GTS) graph to identify features of interest. The GTS graph comprises nodes corresponding to objects described in the remote sensing and geolocation datasets, and edges that indicate geospatial or temporal relationships between pairs of nodes in the nodes. Trajectory information is encoded in the GTS graph by the inclusion of movable nodes to facilitate searches for features of interest in the datasetsmore » « less

Using antennas separated in flight direction to avoid effect of emitter clock drift in geolocation

Patent Ormesher, Richard C.; Bickel, Douglas L

The location of a land-based radio frequency (RF) emitter is determined from an airborne platform. RF signaling is received from the RF emitter via first and second antennas. In response to the received RF signaling, signal samples for both antennas are produced and processed to determine the location of the RF emitter.

Centrifugal contactor with liquid mixing and flow control vanes and method of mixing liquids of different phases

Patent Jubin, Robert T [Powell, TN]; Randolph, John D [Maryville, TN]

The invention is directed to a centrifugal contactor for solvent extraction systems. The centrifugal contactor is provided with an annular vertically oriented mixing chamber between the rotor housing and the rotor for mixing process liquids such as the aqueous and organic phases of the solvent extraction process used for nuclear fuel reprocessing. A set of stationary helically disposed vanes carried by the housing is in the lower region of the mixing chamber at a location below the process-liquid inlets for the purpose of urging the liquids in an upward direction toward the inlets and enhancing the mixing of the liquidsmore » « less

Computing angle of arrival of radio signals

Patent Borchardt, John J.; Steele, David K.

Various technologies pertaining to computing angle of arrival of radio signals are described.
