A Virtual Proving Ground (VPG) for evaluation of CB detectors is being developed by the U.S. Army at Dugway Proving Ground (DPG). The VPG is essentially a combination of computer models for the scene and a detector. The objective is to evaluate the detector performance without requiring expensive field tests. To support the VPG, a general purpose, passive standoff detector model was developed using models from the literature. The important environmental stress variables that affect the detector output signal are determined using 2 level factorial design experiments. An example 2 level factorial design experiment with ILSCAD data is discussed. The model parameters are determined with various detector characterization tests. These include spatial responsivity measurement, wavenumber scale calibration, line shape function measurement, and spectral response measurement. An overview of the detector model and the characterization procedures is discussed.
