Paper Abstract

Target acquisition range predictions are based upon system MTF analysis. Johnson linked cycles on target (sounds like an MTF), N50, to detection, recognition, and identification (DRI). Over time, models changed with V50 replacing N50. Not surprisingly, the DRI V50 values changed as the models evolved. Current DRI V50 values appear to be target specific. What is changing is the detail size needed for DRI – not V50. Rather than have a V50 for each task, use V50 = 2 for detecting specific target features. As the feature size decreases, target detail becomes more prominent leading to recognition and identification.
