Abstract : The theory of the regulatable directional (RNP) method, which was developed at the seismic laboratory of MINKh, was further developed on the base of the frequency theory of signals. As a result it is possible to synthesize RNP systems by determining in the best way the necessary parameters. Formulas are derived for the resolution of the RNP Method. The absence of interference of the amplitude increments, in the form of which waves are recorded on the summing tape, is a necessary condition for complete resolution of two waves by the RNP method. Here interoplation of summarized recordings by their amplitudes in the interval between the positions of cophase summation of superposed waves must ensure that at least one summarized recording with zero amplitude increments for both waves can be obtained.
