ORTHOGONAL CODING SOURCE AND RECEIVER Russian patent published in 2017 - IPC G01V1/28 G06F17/50 

FIELD: geophysics.

SUBSTANCE: method of inversion of simultaneous encoded geophysical data sources for evaluation of model parameters (41) of physical properties,especially adapted for examinations without geometry registration system of stationary receivers, such as for instance marine seismic survey with moving source and receivers. Function (32) coding used for sources to generate one or more samples of simultaneous encoded data sources (35), as well as for their simulation (34) are orthogonal or pseudo orthogonal in relation to cross-correlation. Besides receivers are also encoded, wherein coding of receiver is configured to make certain receiver less sensitive to sources, that is not listened during examination (38). Coding function can be time band filters, different from each other along central frequency, phase or both.

EFFECT: effectiveness of method can be additionally increased by grouping several sources in super-source, grouping corresponding samples in super-sample and then using said encoding strategy.
