Abstract:
Method for separating responses of multiple transmitters m a controlled source electromagnetic survey by using mutually orthogonal transmitter waveforms and transforming the combined response to the frequency domain (144) The mutual orthogonality can be based disjoint frequency spectra or on phase encoding of a common waveform element (FIG. 14).
