N2 - In this paper, we evaluate thresholding algorithms applied in wavelet filter bank (FB) based passive detection in radar and sonar systems. Addressing a random emission with unknown parameters, the emission and the received signal are modelled by a Gaussian process with unknown mean and variance. The wavelet FB decomposes the received signal into subchannels. A decision on the absence and presence of the emission is then made by thresholding against the FB outputs. Formulae are derived to prove the detection performance using different thresholding strategies. A graphical comparison of the detection performances with different strategies and in different scenarios is presented. Design principles are derived under this wavelet FB based detection framework.
