Dear all,
I want to calculate B⊥, crit for Sentinel1A. As I know its formula is:
B⊥, crit = − (W ρ λ tan(θ − α))/c
c: The speed of light,
W: The bandwidth of the SAR signal,
ρ: The range to the object on ground,
λ: The wavelength of the SAR signal, (λ=0,055m)
θ: The incidence angle,
( Incidence angle range for interferometry mode (IW): 29.1° - 46.0°
incidence angle for IW2 is from 36.47 to 41.85.)
α: The local surface slope (as I am working on ice, it is zero)
My Question:
I know all parameters for Sentinel1A except W (The bandwidth of the SAR signal) and ρ (The range to the object on ground).
Is there anyone can guide me?
Cheers,
Marjan
