Record 2 2011-04-20

English

Subject field(s)
  • Radio Transmission and Reception
  • Telecommunications Facilities
DEF

A radar beam pattern designed to give uniform signal intensity in echoes from distant and nearby objects.

OBS

It is generated by a spun-barrel reflector. The beam intensity varies as the square of the cosecant of the elevation angle.

Key term(s)
  • cosecant squared beam

French

Domaine(s)
  • Émission et réception radio
  • Installations de télécommunications

Spanish

Campo(s) temático(s)
  • Radiotransmisión y radiorrecepción
  • Instalaciones de telecomunicaciones
DEF

Haz estrecho vertical en forma de abanico en el que la intensidad de campo radiada en cualquier dirección dentro de una cierta gama angular es proporcional al cuadrado de la cosecante del ángulo superior o inferior al plano horizontal a través del origen del haz.

OBS

Este tipo de haz, utilizado en un equipo radar T-R común, proporciona intensidad de señal casi uniforme para los ecos recibidos desde objetos cercanos y lejanos en cualquier otro plano horizontal dentro de la dirección del haz.

Record 3 2002-08-14

English

Subject field(s)
  • Radio Transmission and Reception
  • Telecommunications Facilities
DEF

An antenna which gives a narrow vertical fan-shaped beam such that the power flux density radiated (and received) in any direction, within a certain angular range, is proportional to the square of the cosecant of the angle above or below the horizontal plane through the origin of the beam.

OBS

Commonly used in airborne reconnaissance radar because it gives approximately uniform signal intensity for echoes received from near and distant targets on the Earth's surface and within the azimuthal coverage of the beam.

French

Domaine(s)
  • Émission et réception radio
  • Installations de télécommunications

Spanish

Campo(s) temático(s)
  • Radiotransmisión y radiorrecepción
  • Instalaciones de telecomunicaciones
DEF

Antena que proporciona un haz estrecho vertical en forma de abanico en el que la intensidad de campo radiada(y recibida) en cualquier dirección dentro de una cierta gama angular es proporcional al cuadrado de la cosecante del ángulo superior o inferior al plano horizontal a través del origen del haz.

OBS

Utilizada comunmente en radar aerotransportado de reconocimiento porque proporciona intensidad de señal casi uniforme para los ecos recibidos desde objetivos cercanos y lejanos en la superficie terrestre dentro de la cobertura en acimut del haz.
