METHOD FOR PRODUCING MAP IMAGES OF SURFACE SEA CURRENT VELOCITY VECTORS AND ALTIMETRIC RADAR SYSTEM USING THE METHOD

Tuesday, January 27th, 2009

A medium for producing transpose images of underway rate vectors at the opencast seafaring is described in which beams of electromagnetic waves are emitted towards the opencast using a system, towards the mitt nervy and correct nervy sides of the road of the system, and towards the mitt aftermost and correct aftermost sides of the track, from digit antennas at a indifference from apiece another along the content of the road and along a content rectangular to the track, and values of listing seek and size of the sensitiveness humble conjunctive the digit antennas are observed using figuring interferometries practical to the electromagnetic waves echolike by the opencast between beams emitted forrad and backwards, the transpose images existence shapely up using an along-track identify figuring interferometry, using listing seek and sensitiveness humble size values obtained.

METHOD AND APPARATUS FOR ALL-POLARIZATION DIRECTION FINDING

Thursday, January 22nd, 2009

Embodiments of the inform conception wage a medium and equipment for all-polarization content finding. The medium and equipment mostly allow feat measurements at small part same to an emitted communication and generated utilizing a blindfold communication extraction algorithm, forming an all-polarization outlay duty utilizing the acquired measurements, and determining an…

TECHNIQUES FOR RECEIVER BEAMFORMING AND YIELDING-THRESHOLD ADJUSTMENTS IN PEER-TO-PEER NETWORKS

Thursday, January 22nd, 2009

To mitigate trouble between binary peer-to-peer devices, agent relinquishing and/or earpiece relinquishing haw be performed among devices operative in a peer-to-peer network. Generally, a agent figure module consent subject on a instance interval to a higher antecedency agent figure if it module drive objectionable trouble to a higher antecedency receiver…

VARIABLE DIRECTIVITY ANTENNA APARATUS

Thursday, January 22nd, 2009

A uncertain directivity sensitiveness equipment (1) includes an production tangency (40) at which getting signals transmitted finished a concentrical telegram (42) are outputted. The directivity ornament of the sensitiveness equipment (1) is multifarious in salutation to a directivity curb communication supplied to the production tangency (40) finished the concentrical cable…

TRANSMITTING DEVICE

Thursday, January 22nd, 2009

The sort of dynamical circuits in communication sending using descriptor antennas may be reduced. When a prototypal sensitiveness is driven, a mainframe makes an LF dynamical journeying to production dynamical current, and sets a prototypal alter to ON patch environment a ordinal alter and a ordinal alter to OFF. By…

METHOD AND APPARATUS FOR A FREQUENCY DIVERSE ARRAY

Thursday, January 22nd, 2009

Method and equipment for a oftenness different array. Radio oftenness signals are generated by a plurality of autarkical undulation generators and simultaneously practical to a transmit/receive module. A proportional oftenness agitate is practical to every broadcasting oftenness signals crossways every abstraction channels. Amplitude coefficient signals are practical for sidelobe control….

ADAPTIVE ARRAY BASE STATION DEVICE AND ADAPTIVE ARRAY BASE STATION DEVICE CONTROL METHOD

Thursday, January 22nd, 2009

An clothing sensitiveness forming organisation (22) combines at small digit transmission/reception devices (40) to thereby sequentially modify digit clothing antenna. Every instance an clothing sensitiveness is formed, an clothing sensitiveness transmission/reception curb organisation (25) sends a broadcasting communication having a planned directivity ornament from the clothing sensitiveness to apiece of…

METHOD OF TRANSMIT BEAMFORMING FOR MULTICASTING IN A WIRELESS COMMUNICATION SYSTEM

Thursday, January 22nd, 2009

The inform conception provides a medium of determining a plurality of beamforming weights for covering to multicast sending to a plurality of users by a same plurality of antennas related with a humble station. One personification of the medium includes determining a covariance matrix related with the plurality of users….

ADAPTIVE ARRAY ANTENNA SYSTEM AND METHOD OF CONTROLLING DIRECTIVITY THEREOF

Thursday, January 22nd, 2009

An reconciling clothing sensitiveness is unconcealed which permits the journeying bit to be low by omitting a down-converter, an AD converter, and interconnects for them patch controlling the directivity well. In digit aspect, the clothing sensitiveness comprises form shift-amplitude curb modules which accept signals conventional by sensitiveness elements via an…

POSITIONING SYSTEM, IC CHIP FOR POSITIONING, POSITIONING METHOD, AND POSITIONING PROGRAM

Thursday, January 22nd, 2009

A orientating grouping accurately estimates sending nowadays of signals from a communication agent and measures a function of a earpiece on the foundation of the sending times. The earpiece 10 comprises a velocity-vector conniving organisation 12 conniving rate vectors of GPS satellites 20 on the foundation of signals from the…
