2.11.5 The Derivation of Backscattering
Coefficients and RCSs in ASAR Products
ASAR detected ground range projected products
will be delivered as radar brightness (i.e.
elevation antenna pattern and range spreading
loss corrected but no incidence angle
compensation) while complex slant-range products
will be delivered without any cross-track
radiometric corrections.
