Abstract

Предложены способ и система для создания микросейсмического события в среде в результате нелинейного взаимодействия, предназначенные для получения характеристик среды. Способ включает в себя генерацию с помощью первого акустического источника первого кодированного акустического сигнала, содержащего первое множество импульсов, скомпонованных в виде временной последовательности, при этом каждый импульс содержит модулированный сигнал на центральной частоте; и генерацию с помощью второго акустического источника второго кодированного акустического сигнала, содержащего второе множество импульсов, скомпонованных в виде временной последовательности, при этом каждый импульс содержит модулированный сигнал, и центральная частота модулированного сигнала в каждом импульсе во втором множестве импульсов равна выбираемому относительному значению d центральной частоты модулированного сигнала для соответствующего импульса в первом множестве импульсов. Способ также включает в себя прием с помощью приемника детектируемого сигнала, включающего в себя третий сигнал, генерируемый вследствие процесса нелинейного смешения первого акустического сигнала и второго акустического сигнала в зоне смешения; выполнение с помощью процессора обработки данных для принимаемого сигнала или корреляции с эталоном кодированного сигнала или того и другого, для извлечения третьего сигнала, генерируемого вследствие процесса нелинейного смешения, из шума или из сигналов, генерируемых вследствие процесса линейного взаимодействия, или того и другого, для получения сигнала имитируемого микросейсмического события, происходящего в
