    • Method for separating signals recorded by a seismic receiver and generated with at least two vibratory seismic sources driven with no listening time. The method includes receiving seismic data that includes data d recorded by the seismic receiver and data related to the first and second vibratory seismic sources; computing a source separation matrix based on the data related to the first and second vibratory seismic sources; calculating first and second earth impulse responses HA and HB corresponding to the two vibratory seismic sources, respectively, based on the data d recorded by the seismic receiver, the data related to the two vibratory seismic sources and the source separation matrix; and separating the signals recorded by the seismic receiver based on the first and second earth impulse responses HA and HB such that signals the two vibratory seismic sources are disentangled.
    • 用于分离由地震接收机记录并由至少两个振动地震源产生的信号的方法,所述至少两个振动地震源不受聆听时间驱动。 该方法包括接收包括由地震接收机记录的数据d和与第一和第二震动震源有关的数据的地震数据; 基于与第一和第二震动震源相关的数据计算源分离矩阵; 基于地震接收机记录的数据d,与两个振动地震源相关的数据和源分离矩阵,分别计算对应于两个振动地震源的第一和第二地球脉冲响应HA和HB; 以及基于第一和第二地球脉冲响应HA和HB分离由地震接收机记录的信号,使得两个振动地震源的信号解开。
