Hi All,
We are working on a seismic refraction project where we are using 113 Geophones of 4.5 Hz. The geophone spacing is 2.5 m and the record length is kept 1 seconds. Aim is to record first arrival for refraction and also surface wave for MASW processing. The sampling interval is kept as 0.25 millisecond.
I am looking forward to know the principle for calculating sampling interval based on the record length, geophone numbers and frequency. Seismodule controller is being used for data acquisition.
