Abstract :
The measurement centre of microwave electronic distance-measuring instruments (EDMIs) is affected by antenna VSWR in the transmit plane. This results in the measuring centre of the instrument changing with temperature as the frequency of the microwave transmitter source changes. A new technique is described which virtually eliminates this source of error.
