Modified Savage and modified rank squared nonparametric detectors
Abstract
Attention is given to a modified version of the basic Savage statistic and the operation of a modified Savage nonparametric detector using this modified statistic. A detector employing a modified rank square statistic is described. The asymptotic relative efficiency of the modified detectors is found for chi-square, Rician, and log-normal signal fluctuations, assuming Gaussian background noise. These efficiencies are compared to the generalized sign and Mann-Whitney detectors. The derived results are also compared to the results of a computer simulation.
