Abstract

This report describes the development of a measurement system to calibrate power flux density and field strength probes for use in pulsed applications such as radar. The additional uncertainties due to the measurement of the peak and average power have been analysed and the system has been used to measure the performance of typical probes. Those probes employing thermocouple detection showed very good performance, as did a frequency selective probe. A diode based probe, although exhibiting large variations in sensitivity depending on the pulse parameters and applied level, can now be corrected by calibration at NPL. In common with the more expensive frequency selective probe, its fast response and peak-hold facility offers scope for the measurement of rotating radars.
