What is coherent noise? Coherent noise refers to noise wavetrains that display coherence in the form of systematic phase relationships between adjacent traces. For example, source-generated seismic noise (e.g., ground roll, shallow refractions, reverberations, multiples, etc.) usually is coherent. In exploration seismology, the terms source-generated noise and signal-generated noise are the same and can be used interchangeably.
