Update on Radar Detection Probabilities and their Calculation

In the 1995 paper entitled Radar Detection Probabilities and their Calculation, chi-square density functions, normalized with respect to the clutter variance, were used for the clutter density. While mathematically correct, it makes better physical sense to use clutter constant false-alarm rate (CFAR) density functions both there and in the 1999 paper, Generalized Radar Clutter Model, that are normalized with respect to the receiver noise, as is done with the target models. We update the results of these papers by redoing the relevant equations with these more appropriate clutter density functions.
