  • The data processing in complex cepstrum domain can restrain the echo-like multi-reflection wave. The TDR (Time Domain Reflectometry) waveforms are analyzed in complex cepstrum domain in this paper. By filtering in complex cepstrum domain, the multi-reflection waves are eliminated. Used the cepstrum analysis, the travel time on the probes are determined. Apparent permittivity of soil is inversed with the cepstrum analysis. The results inversed with the complex domain filter method is more accurate than tangent-lines method.
