Abstract: The proposed methodology and the corresponding model coherent and noncoherent detection of navigation signals in the presence of interfering reflections from background noise oscillations. The method consists in accounting for the differences between a distorted form of the navigation signal due to interfering reflections and correlation function of noise in the output part of an RF receiver. This circumstance allows to use the integrated (dual) processing the received navigation signal when it is detected with an automatically adjustable threshold decision. It is shown that this combined detection method virtually neutralizes the interfering signal, even with significant temporal overlaps with the navigation signal
