Le système se fonde sur des batteries d'antennes, qui suivent à la trace tous les téléphones portables présents dans la cellule. De telles batteries sont déjà couramment utilisées dans nombre de systèmes, notamment des systèmes radar ou de télécommunication satellitaire.

CONT

Transmission avec poursuite directionnelle. Une batterie d'antennes transmet vers tous les utilisateurs de la cellule à tour de rôle.

OBS

Par opposition à la transmission standard où une seule antenne transmet dans toutes les directions.

Record 5 2007-01-31

English

Subject field(s)
  • Satellite Telecommunications
  • Radar, Radio Guidance and Goniometry
  • Spacecraft
DEF

[An antenna] equipped with distributed transmit/receive modules which provide distinct transmit and receive beams.

CONT

The most significant difference between RADARSAT-2 and RADARSAT-1 payload technology is that RADARSAT-2 uses a fully-active phased array antenna, rather than the passive slotted waveguide antenna used by RADARSAT-1. Fully-active phased arrays offer a number of very significant benefits over passive antenna, but they also add great complexity. ... The phased array is made up of 512 individual radiating elements, organized into 16 columns (picture below shows a single column) along the 15-metre antenna length, each with 32 rows across the 1.5- metre width. The phase shifters and amplitude control are built into the Transmit/Receive (T/R) modules, which feed the radiating elements. Each column has a computer that controls the 32 T/R module settings and these 16 computers are all linked to another computer (in the spacecraft bus) that orchestrates the overall antenna behaviour.

OBS

active array antenna: term officially approved by the RADARSAT-2 Terminology Approval Group (RTAG).

Domaine(s)
  • Télécommunications par satellite

DEF

Antenne composée de plusieurs éléments rayonnants, installée à bord d'un satellite et destinée à la transmission et à la réception des données.

CONT

Le radar à synthèse d'ouverture [de RADARSAT-2] comprend un système électronique sophistiqué qui alimente une antenne active à réseau d'éléments en phase qui consiste en 512 modules de transmission-réception (TRM) avec des réseaux de distribution de puissance et fréquences radio.

Record 8 2001-07-31

English

Subject field(s)
  • Telecommunications Facilities
CONT

... The smart antenna consists of an eight-element uniform linear array, eight transceiver trains and the adaptive antenna array processor (AAAP). ... The AAAP performs four main tasks: (1) Direction-of-arrival (DOA) estimation from the received input data in the uplink with a high-resolution estimator. (2) A DOa identification classifies the DOAs and decides whether a wavefront (DOA) belongs to a user or to an interferer. (3) A tracker follows each nominal DOA (multipath component) of the user. The tracker does not only include averaging of the DOAs, but also measures the reliability of each multipath. (4) Signal reconstruction and beamforming, where a b beamforming algorithm forms an antenna pattern with a main beam steered into the direction of the strongest reliable user multipath, while simultaneously minimizing the influence of the interfering wavefronts.
