English

Subject field(s)
  • Radar, Radio Guidance and Goniometry
  • Spacecraft
  • Remote Sensing
DEF

The range direction of a side-looking radar image as projected onto the nominally horizontal reference plane, similar to the spatial display of conventional maps.

CONT

For spacecraft data, an Earth geoid model is used, whereas for airborne radar data, a planar approximation is sufficient. Ground range projection requires a geometric transformation from slant range to ground range, leading to relief or elevation displacement, foreshortening, and layover unless terrain elevation information is used.

OBS

ground range: term officially approved by the RADARSAT-2 Terminology Approval Group (RTAG).
