system for geophysical exploration uses a single source (30) which emits signals within the aggregate octave.the source is contained in the composite signal from the u043au0430u0447u0430u044eu0449u0435u0439u0441u044f frequency, are composed of two or more signals with u043au0430u0447u0430u044eu0449u0435u0439u0441u044f frequency, one of which pok u0440u044bu0432u0430u0435u0442 lower octave (10).while other signals with u043au0430u0447u0430u044eu0449u0435u0439u0441u044f frequency cover the rest of the bandwidth.the signals covering the lower station, are reduced in the case of linear time u043au0430u0447u0430u043du0438u044f frequency is proportional to the square root of the relationship of speed u043au0430u0447u0430u043du0438u044f the frequency of signalsto cover the top end, the speed u043au0430u0447u0430u043du0438u044f frequency signal covering the bottom end. the signals are transmitted simultaneously.the u0441u043eu0441u0442u0430u0432u043du043eu043cu0443 u043au0430u0447u0430u043du0438u044e frequency power spectrum transfer remains the same as for the sinusoidal wave with frequency u043au0430u0447u0430u043du0438u0435u043c, passing across the floor efe frequenciesbut at the same time, in order to maintain a uniform spectrum at lower frequencies require reduced peak power and the radiator. it can be reduced and the size of equipment.the application was published, together with the report on the international market.
