The analysis of the known methods and navigation systems of flying robots (FR) was performed. Among them, because of a number of shown below reasons, the most preferable are passive combined correlation-extreme systems which implement the survey-comparative method. A basic model for the radiometric channel operation of the correlation-extreme navigation systems is proposed. The factors that lead to distortions of the decisive function formed by the combined correlation-extreme navigation system of flying robots in a developed infrastructure are allocated. A solution of the problem of autonomous low-flying flying robot navigation in a developed infrastructure using the radiometric channel extreme correlation navigation systems (CENS), when the size of the solid angle of associated object is much larger than the size of the partial antenna directivity diagram (ADD), is proposed. The appearance possibility of spurious objects that are close in parameters (geometric dimensions and brightness) to the anchor object, depending on the current image sight geometry formed by the optoelectronic channel of the combined CENS, is taken into account.
