Claim One:
1. A method for processing incoming seismic-trace signals acquired during seismic prospecting utilizing plural initiations of a seismic source, comprising the steps of: improving the signal to noise ratio in incoming seismic trace signals by selecting an exponent from a group of exponents including 0, 1, 2, 4 and 8, for use with a remotely deployed field recorder for inverse power weighting the incoming seismic trace signals based on the ratio of the expected level of true earth response seismic signals, which can include reflections, refractions or ground roll, and the expected level of ambient noise, which can include burst noise; dividing each incoming seismic-trace signal into a series of component seismic-trace signals each within a time window of a predetermined length, each component seismic-trace signal comprised of samples of the incoming seismic-trace signal; calculating a respective weighting value for each respective component seismic-trace signal based on the selected exponent; applying the respective weighting values to the respective component seismic-trace signals; and summing the corresponding weighted component seismic-trace signals from plural initiations of the seismic source for forming a composite seismic-trace signal.
