Abstract : The system of interest here includes the combined nonlinear transformations of normalization and or-ing in the data processing chain. The required threshold settings for specified false alarm probabilities are determined, as well as the required input signal-to-noise ratios for specified detection probabilities. Specializations to normalization or or-ing alone are available by particular choices-Of parameter values built into the models. When the sizes of the transformations are changed, that is, the amount of normalization and/or or-ing, the thresholds will also have to be changed if the earlier probabilities are to be maintained; these options are included in the first program listed. In addition, the possibility of changing the number of thresholds, at the same time that the sizes of the nonlinear transformations are changed, is included in the second program listed. Furthermore, four alternatives are allowed for selecting the spacing of the thresholds, namely, equispaced in power, equispaced in decibels, preset normalized thresholds, or preset probabilities.
