    Fidelity Vibroseis Seismic Data Acquisition (HFVS) is to simultaneously shoot
    at multi-positions with multi-sources, which greatly improves the acquisition efficiency.
    Simultaneous shooting leads to the increase of adjacent interference on record
    and the decrease of the S/N ratio of seismic data, so raw record requires
    source separation before application. The linear sweep signals shoot by Vibroseis
    was used to simulate 2D seismic data acquisition with HFVS method. Then, phase
    encoding was carried out on source signals and several aliasing records were
    obtained by forward modeling. Source detection signal and seismic record were
    adopted to gain the transfer function of every frequency points of the physical
    path between shot point and every receiving point. Then transfer function was
    taken as source detection signal, by this means, the single-shot seismic record
    after separation can be obtained. By comparing separated result with
    single-shot forward modeling result, the authors see that the separation results
    of far-shotpoint traces and near-shotpoint traces are both good; moreover, the
    former one is better than the later.
