The equivalent bar target technique for the tasks of detection, recognition and identification proposed by Johnson is used extensively to assess the performance of thermal imagers. However the approach does not enable background information to be incorporated in such an assessment. A new background criterion is therefore proposed which will enable backgrounds to be included in range modelling.
