ABSTRACT:
Guided wave radar (GWR) pulses are launched onto an electromagnetic guide wire using a compact launcher that includes an impedance matching element. The impedance matching element produces reflections that cancel launcher reflections. Short range echoes can be accurately detected after impedance matching. GWR operation in small tanks and in tanks containing low dielectric constant materials, such as propane, can be enhanced with the compact impedance-matched launcher.
