Un radar à synthèse d'ouverture (RSO) est un radar qui effectue un traitement des données reçues afin d'améliorer la résolution azimutale. Le traitement effectué permet d'affiner l'ouverture de l'antenne. On parle donc de synthèse d'ouverture. D'où le nom de ce type de système. Les radars à synthèse d'ouverture sont donc à opposer aux «radars à ouverture réelle» (RAR ou real aperture radar en anglais) pour lesquels la résolution azimutale est simplement obtenue en utilisant une antenne d'émission/réception possédant un lobe d'antenne étroit dans la direction azimutale.  2, record 2, French, - radar%20imageur%20%C3%A0%20synth%C3%A8se%20d%27ouverture

Record number: 5, Textual support number: 1 CONT

Antenna pattern correction. The brightness of the image is affected by the antenna gain variation where the near range will receive maximum power while the far range will receive minimum power. This effect produces an image that varies in intensity (tone) along the range direction across the image. The antenna pattern effect is expressed as the energy returned to the radar and decreases dramatically as the range distance increases. Antenna pattern correction is applied to produce a uniform average brightness across the imaged swath.  3, record 5, English, - antenna%20pattern%20correction

Record number: 6, Textual support number: 1 CONT

The aspect angle... can have a significant influence on the appearance of radar imagery, especially when features in the scene have an organized linear structure, such as agricultural crops or geological structures. When a radar's illumination is oriented perpendicular to geologic features such as faults, lineaments and outcrops, [there is] increased contrast and shadowing of the features in the image results. This is a favourable aspect angle for the image interpreter, as terrain is enhanced. In agricultural applications, fields imaged from different aspect angles may result in different tones on the image because of row or planting direction. Aspect angle can cause imaging geometry to be either enhanced or suppressed.  3, record 6, English, - aspect%20angle

The angle defined by the incident radar beam and the vertical (normal) to the intercepting surface.  3, record 7, English, - incidence%20angle

Record number: 7, Textual support number: 1 CONT

The incidence angle is commonly used to describe the angular relationship between the radar beam and the ground, surface layer or a target. A change of the radar illumination angle often affects the radar backscattering behaviour of a surface or target. The incidence angle changes across the radar image swath; it increases from near range to far range. In the case of satellite radar imagery, the change of incidence angle for flat terrain across the imaging swath tends to be rather small, usually on the order of several degrees. In the case of an inclined surface(slope), the local incidence angle is defined as the angle between the incident radar beam and a line that is normal to that surface. The local incidence angle determining, in part, the brightness, or image tone, for each picture element(pixel) and slope facet, is a key element in the prominent rendition of terrain features in radar imagery.  3, record 7, English, - incidence%20angle

The laser(or lidar) velocimeter [lidar=light radar] operates in a fashion entirely analogous to that of the airborne Doppler weather radars likely soon to be available for detecting turbulence in storm cells. As with radars, the device detects air movements by observing the motion of particles suspended in the air and carried with it. The only significant difference is that a beam of coherent infrared radiation is used to scan ahead of the aircraft, instead of a beam(or series of pulses) of radio energy in the considerably longer-wavelength microwave band. The frequency of the back-scattered echoes or reflections undergoes Doppler shift detection by standard heterodyning techniques, which involve comparing the frequency of the reflected illumination with that of the original laser beam. Any reflecting object or material which has motion relative to the transmitter/receiver will cause a detectable shift in frequency, which can be isolated from the transmitter's own proper motion(over the ground) and thus yield a precise indication of the speed at which the air is moving several hundred metres in front of the aircraft. From this data, it is easy to compute what the air speed of the aircraft will be when it reaches that particular patch of air in a few seconds’ time [and hence detect possible turbulence ahead].  2, record 15, English, - laser%20velocimeter
