A novel low-cost approach for large gray-toned fabric panels for calibrating remotely sensed VIS/NIR/SWIR data

摘要

Large size calibration panels are frequently required as reference points for in-scene calibration of remotely sensed spectral data. However, most commercially manufactured calibration panels are costly and sometimes present spectral crossover problems. The panels described in this report are made from readily available fabrics and can provide a lower cost alternative. Four 5.5 x 6.7 m fabric panels that have nominal reflectance of 85%, 38%, 18% or 3% were tested. These fabric panels cost approximately
