SYSTEM AND METHOD OF IMPLEMENTATION OF SEISMIC RESEARCH BY USING A CONTROLLED SOURCE USING SWIP SIGNALS OF MAXIMUM POWER

摘要

The output signal spectrum of a controlled acoustic source with a sweeping frequency at a given frequency can be controlled by equating the frequency change rate to the desired output power spectrum divided by the square of the source amplitude envelope of the source output signal, while both values are measured at the time after the start of its frequency, when The frequency of the sweep passes through this frequency. The system and method can also be used to compensate for out-of-source propagation effects by dividing the desired spectrum by the propagation effect. The method can additionally be used to obtain the output spectrum of the desired shape from a source operating at maximum output power, or to design a sweep with the shortest possible duration that will result in a spectrum of the output signal of a certain shape and with a specific amplitude.
