The problem of simultaneous positioning of several radio-frequency radiation sources is complicated by the necessity of unambiguous determination of a set of navigation parameters for each source. In this work, we propose an algorithm for eliminating the ambiguity of correspondence of the mutual time delays of the signal propagation. The algorithm is based on the criterion of consistency of the time delays. We consider mutual time delays, which are obtained using and analyzing the mutual uncertainty function of the signals. The conditions of applicability of the algorithm and its resistance to the noise level in the studied channels are analyzed.
