“…Mathematical statements are less known. This work is a continuation of a study initiated in [9] and then developed in [1,[4][5][6]15], where it was always supposed that there is only one source on the plane. In the works [5,6,9] it was supposed that the moment of the beginning of the emission τ 0 is known and the unknown parameter was just the position of the source.…”

The problem of localization on the plane of two radioactive sources by K detectors is considered. Each detector records a realization of an inhomogeneous Poisson process whose intensity function is the sum of signals arriving from the sources and of a constant Poisson noise of known intensity. The time of the beginning of emission of the sources is known, and the main problem is the estimation of the positions of the sources. The properties of the maximum likelihood and Bayesian estimators are described in the asymptotics of large signals in three situations of different regularities of the fronts of the signals: smooth, cusp-type and change-point type.
