[An application that] performs a radiometric balancing on synthetic aperture radar data to compensate for non-uniform illumination in the range direction due to the antenna pattern.

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.
