Demand for higher signal to noise ratio in seismic data is rapidly increasing. In land data ground roll noise has always been a major problem. Coarse spatial sampling makes this kind of noise considerably difficult to attenuate because of aliasing. High density single sensor recording naturally solves the sampling problem. Digital array forming may then be needed for cost reduction or for signal to noise ratio enhancement. To increase the temporal processing bandwidth, Intra Array Statics (IAS) must be applied prior to digital array forming. Here, three methods for estimating intra array statics are proposed and real data examples are shown.
