Three probe reflectometer algorithm for complex coefficient measurements of water quality at microwave frequencies

Three probe reflectometer algorithm for complex coefficient measurements of water quality at microwave frequencies

The complex reflection coefficient (magnitude and phase) are measured using a three probe reflectometer algorithm. The measurement system consists of a Gunn diode source, 1 kHz modulator, attenuator, slotted line, A/D converter and a computer. A slotted line is used to measure three standing wave vo...

總結:The complex reflection coefficient (magnitude and phase) are measured using a three probe reflectometer algorithm. The measurement system consists of a Gunn diode source, 1 kHz modulator, attenuator, slotted line, A/D converter and a computer. A slotted line is used to measure three standing wave voltages corresponding to three probe positions which are one-eighth wavelength apart. Complex reflection coefficient results are reported for two standard liquids, namely, water and methyl alcohol. This measurement system can be used for water quality measurements. © 2003 IEEE.
