REFLECTIVITY MIRROR [3 records]

  • Remote Sensing

Although there are a number of on-board calibration means not all necessary parameters are accessible. These parameters are subject to on-ground calibration and are not supposed to change from ground to orbit. The most important measurements to be done on ground are [:] the measurement of the diffuser BSDF [Bidirectional Scutter Distribution Function] for the wavelength range of interest [;] the characterisation of the polarisation response of the instrument as a function of the optical path(normal observation path and sun observation path), scan mirror position(the scan mirror reflectivity for S and P polarisation is a function of the mirror angle), and wavelength.

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

Colouring or colour-buffing is employed as a final operation after buffing, the purpose being to bring out the full colour and reflectivity of the metal. No metal is removed by this operation. Colour-buffing is applied to all surfaces where a mirror finish is required.
