I’m using PALSAR-2 to do the research,how snap perform when coming to the calibration?
ALOS-2 PALSAR-2 calibration is supported. For SLCs, the calibration factor is offset by 32 dB
Level 1.1: σ0 = 10log10<I2+Q2> + CF -32.0
Level 1.5/3.1: σ0 = 10log10 + CF
I’ve confirmed the formula in official website of PALSAR2.Thank you ,Iveci.
