METHOD FOR MICROSEISMIC MONITORING OF SPATIAL DISTRIBUTION OF EMISSION SOURCES AND SCATTERED RADIATION AND DEVICE FOR REALIZATION OF SAID METHOD Russian patent published in 2006 - IPC G01V1/00 

FIELD: geophysics, possible use for localization of sources and monitoring their spatial distribution and radiation parameters.

SUBSTANCE: method includes registration of wave noise seismic field with component of radiation from emission and scattering sources by seismic receivers, mounted in observation points. Three-component or single-component seismic receivers are utilized. Presence of emission and/or scattered radiation sources is detected with consideration of value of 95% trust interval of image brightness estimate for wave field, represented by random diffusion interference δ_S, value of trust interval is determined by time of signals accumulation and number of registration channels. Estimation S of spatial distribution of image brightness is performed, which reflects three-dimensional distribution of emission power of emission and scattering sources. Criterion of presence of emission and/or scattering source in environment - exceeding of value of absolute value S in query point of value of trust interval δ_S, |S| ≥ δ_S. Device contains K receiving channels, each one of which is made of signals transformer, amplifier, analog-digital converter, preliminary processing block and data transmission block. Device has processor for coherent processing of signals, registration device, block for computing temporal delays, block for computing output angles for the seismic beam, controlling block, detecting block, input of which is connected to output of coherent processor, and output - to input of registration device.

EFFECT: increased resolution capacity, increased detection sensitivity, increased trustworthiness of results.
