Angle-dependent Least-squares Imaging of Incoherent Wavefields

In traditional seismic acquisition, temporal overlap between the recordings of consecutive shots is avoided. In this paper we will investigate the proposal to abandon this acquisition constraint by introducing dense source distributions in an overlapping fashion (’blended acquisition’). The result is an improved source space with a favorable azimuth distribution. We will show that blended measurements can be directly used in an angle-dependent migration process with a multi-shift least-squares imaging condition, such that a densely sampled illumination is obtained in the ray parameter domain.
