Description: In the artical, the generalized Bayessian theory, providing the processing algorithms for fast varying conditions is begun to be created. In the paper we consider variants of calculating the false alarm probabilities for the devices of their stabilization. For this purpose, the new Pareto – Gaussian a priory model of total interference intensity is therefore reasoned. Investigation of its use in CFAR and STAP theories is begun.
Keywords: space time adaptive processing, constant falls alarm rate, limited falls alarm rate
