  • METHOD FOR ECHO PROCESSING IN TIME-OF-FLIGHT OR LEVEL MEASUREMENT SYSTEMS
    Publication number: 20040233783
    Abstract: A method for processing echoes in a time-of-flight ranging system or level measurement system. The method comprises an initial noise floor level and identifying potential echoes in an echo signal above the initial noise floor level and a noise signal below the initial noise floor level. One or more portions of the initial noise floor level are modified and an adjusted noise floor level is generated by applying a cubic spline algorithm to the modified portions and the initial noise floor level. The adjusted noise floor level is then used to identify valid echoes in the echo signal and generate an echo signal profile.
