DLR's Calibration Home Base for Imaging Spectrometers (CHB)

Kurzfassung

The Calibration Home Base (CHB) of the German Aerospace Center (DLR) is acalibration laboratory for imaging spectrometers. Originally developed forairborne sensors, CHB equipment has since been used to calibrate instrumentsdeployed on a variety of platforms, including satellite and ground-basedsystems. Covering the spectral range from 380 nm to 2500 nm, the CHB providesinstrumentation and expertise for calibrating key performance parameters ofimaging spectrometers - including radiometric, spectral, geometric, andnon-linear characteristics, as well as temperature dependence, stray light, andpolarimetric response. Most calibration processes are automated and supported bya comprehensive software suite that streamlines measurement execution, dataanalysis, level-1 processing, and sensor simulation. For more than a decade,DLR's HySpex imaging spectrometers have undergone regular calibration updatesand improvements, leading to enhanced CHB capabilities and improved dataquality.
