1. A method comprising:
acquiring, using a seismic survey, prestack single sensor seismic data;
representing traveltime moveout of the prestack single sensor seismic data locally as a second-order curve;
calculating, using the prestack single sensor seismic data, local kinematic parameters that define the second-order curve, wherein calculating the local kinematic parameters comprises:
estimating the local kinematic parameters on a sparse estimation grid less dense than an acquisition field grid of the prestack single sensor seismic data, wherein estimating the local kinematic parameters comprises scanning one or more trajectories along the sparse estimation grid to select a trajectory with a threshold coherency defined by a maximum value of a semblance function; and
interpolating the estimated local kinematic parameters from the sparse estimation grid to a dense estimation grid; and
performing, based in part on the local kinematic parameters, wavefield transformation on the single sensor seismic data to generate enhanced prestack single sensor seismic data.
