Single passive location and navigation Doppler-temporal methods (for example, in radio reconnaissance missions of ground, abovewater, air and space objects), manipulating with periodic signals and focused on measurement capability of received signal Doppler frequency continuous displacement at the observation point, resulting from movement of either emission source or observer, are known. Herewith measurements can be carried out on any characteristic frequency of radiated periodic signal spectrum (for example, center frequency) or by modulating function, as well as by comparison of arrival moments of consequent impulse fronts with provision for known period. Trajectory parameters of either source or observer are succeeded to find, without recourse to direction-finding measurements, by cycle period (at the observation point) relative to base period. All known Doppler-temporal methods are based on «basis synthesis» conception that gives rise as a final result to formation of several observation points on motion trajectory and availability of known multiposition location techniques (for example, triangulate, differential-ranging and trilaterational). Herewith generally such trajectories (as, for example, air standing patrol or orbital) are conventionally considered that in some observation segments can be approximated by straight-line uniform motion model with suffices to practice accuracy. However, enumeration of a priory information about moving object velocity magnitude (either source or observer) is matter of principle for all known time-andfrequency methods, but it is not possible for practice on frequent occasions. Therewith there are no in known papers some sort experiment results supporting efficient use possibility of Doppler-temporal methods, taking into account signal periodicity, for radio contact some representative conditions.Present article is appealed to reduce mentioned disadvantages and gaps.
