Laser remote sensing measurements of natural target reflectivities

The application possibilities of active infrared spectroscopy to remote sensing of soil and rock types and surface soil moisture was investigated in laboratory work and flight campaigns. For the flight measurements the DIALEX instrument, a profiling laser spectrometer with tunable CO2-lasers (9 to 11 microns) was used. The differential reflection data of flight measurements agree with laboratory results. The mean deviation between these data is 15%. Especially for large homogeneous test sites like grass land, ploughed fields and lake Ammersee the mean deviation is 15%.
