N2 - In this paper, we propose a novel semi-parametric target detector to be used within the general detection framework of the likelihood ratio test for the additive signal model. A tree-structured probabilistic graphical model is used to obtain lower dimensional representation of the background probability density function. The overall density estimation problem, which is reduced to finding univariate and bivariate estimates, is solved using the Gaussian mixture model. Target detection experiments are carried out using the hyperspectral airborne 'Viareggio 2013 trial' data set. The detector is shown to provide promising results for the detection of the targets of interest deployed in the scene.
