  • Method and apparatus for obtaining high accuracy simultaneous calibration of signal measuring systems
    Patent number: 4613821
    Abstract: Method and apparatus for high accuracy simultaneous calibration of electrical measuring systems wherein a calibration signal which has frequency spectra which interleave but do not interfere with the data spectra is injected into the electrical system during data acquisition to simultaneously correct for the response of the particular detection system. In a particular geophysical application, a calibration signal at a source system or receiver system, or both, is injected into each individual system as the data and calibration signals are measured so that an overall system response can be applied to the data signals in order to remove system response effects therefrom.
