Experimental Measurements of Radiometric LADAR Calibration Targets

摘要

The problems related to experimental measurements of LADAR calibration targets are often discussed in terms of expected signal returns and related statistics with insignificant regard to target dynamics. Laboratory measurements of specular and diffuse radiometric calibration targets have been undertaken in order to obtain well-controlled optical cross section data for model development and validations with a goal of 20% radiometric accuracy. Factors, such as speckle and laser noise, that have some bearing on this measurement have been recently quantified and indicate that calibration target dynamics may be an important variable in assigning overall radiometric accuracy.
