"Transmission-line theory is applied to the calculation of the transmission and reflectionerrors which occur in a transmission line that has small impedance discontinuities along itslength. The discontinuities are typical of those arising in coaxial cables as a result of the manufacturing process. Errors arising from mismatches in the source and terminating impedances are also calculated. The results indicate that errors in phase up to several degrees are possible in the CRC High Frequency Direction Finding array, due to such imperfections. The solution to the inverse problem of computing the transmission line impedance profile from measurements of the reflection characteristics of the line is also outlined, and some restrictions which apply when the reflection properties are measured with swept-frequency equipment are derived"--Abstract, page 1.
