The antenna of modern airborne weather radars are stabilized by means of:
  • A
    feedback from the antenna accelerometers.
  • B
    artificial gravity switches.
  • C
    inputs from the aircraft' s attitude system.
  • D
    mercury switches.
The Airborne Weather Radar (AWR) is normally mounted in the nose section and the centre postion is aligned with the fore-aft axis of the aircraft. The aerial, regardless of the type, is fitted on a gimbal system that stabilises the aerial with the horizon both in roll and pitch directions. Therefore, regardless of the attitude changes of the aircraft, the antenna is kept in the same attitude relative to the horizon. This feature is achieved with the aircraft inertial attitude reference system and is to ensure that the radar picture is not distorted or lost during manoeuvres of the aeroplane.
