General information: Radar name: AIRSAR Number of looks: 16 Site: Barrax Date: July 14 1991 TIME GMT: 9:10:56 Information on calibration: Polarimetric data were provided by using standard JPL calibration techniques, with the aid of thriedal corner reflectors deployed in the field. Each file (except some of them, read note) is divided in three blocks of 323 lines: 1 Field identification 2 Frequency (GHz) 3 Number of pixels 4 Mean value of the backscatering coefficient for HH polarization (dB) 5 Standard desviation 6 Mininum value (dB) 7 Maximum value (dB) 8 Mean value of the backscatering coefficient for VV polarization (dB) 9 Standard desviation 10 Mininum value (dB) 11 Maximum value (dB) 12 Mean value of the backscatering coefficient for HV polarization (dB) 13 Standard desviation 14 Mininum value (dB) 15 Maximum value (dB) 16 Mean value of the HH-VV Module (dB) 17 Standard desviation 18 Mininum value (dB) 10 Maximum value (dB) 20 Mean value of the HH-VV Phase (degrees) 21 Standard desviation 22 Mininum value 23 Maximum value 24 Mean value of the HH-HV Module (dB) 25 Standard desviation 26 Mininum value (dB) 27 Maximum value (dB) 28 Mean value of the HH-HV Phase (degrees) 29 Standard desviation 30 Mininum value 31 Maximum value 32 Mean value of the HV-VV Module (dB) 33 Standard desviation 34 Mininum value (dB) 35 Maximum value (dB) 36 Mean value of the HV-VV Phase (degrees) 37 Standard desviation 38 Mininum value 39 Maximum value 40 Incidence angle (degrees) 41 Standard desviation 42 Mininum value 43 Maximum value 44 - 83 Histogram of the backscatering coefficient for HH polarization 84 - 123 Histogram of the backscatering coefficient for VV polarization 124 - 163 Histogram of the backscatering coefficient for HV polarization 144 - 203 Histogram of the HH-VV Module 183 - 283 Histogram of the HH-HV Module 224 - 323 Histogram of the HV-VV Module 324 blank About the histograms: Modules: 40 samples between 0 and 1 (fixed values) Angle: 40 samples between -180 and +180, step 9 degrees NOTE: Files corresponding to the crops: BRC1, BRC2, BSC1, BSC3, BAL1, BSD1, BSD2 only have two blocks of 323 lines each (as those fields have very low roughness, Band P data values are not significative)
