English

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

A radar that opperates in the microwave range and that allows for the conversion of acquired data into bidimensional images.

OBS

Typical bandwidths for an imaging radar are in the range 10 to 200 MHz. At the Earth's surface, the energy in the radar pulse is scattered in all directions, with some reflected back toward the antenna. This back scatter returns to the radar as a weaker radar echo and is received by the antenna in a specific polarization (horizontal or vertical, not necessarily the same as the transmitted pulse), for later processing and display as an image.

OBS

SAR imaging radar: term officially approved by the RADARSAT-2 Terminology Approval Group (RTAG).
