The development of an impulse measurement system for determining the transfer characteristics of microwave radiators and absorbers is described. A theoretical and experimental investigation of the balanced TEM horn, monopole stub, balanced dipole, and balanced loop as impulse field sensors is discussed. Details are given of the sensors time domain measurements and the computer signal processing techniques used to determine spectral characteristics. Transfer function measurements of the sensors are presented and compared with the theory. Estimates of measurement accuracies are determined. The validity and usefulness of time domain, digitally processed measurement method is established. It is found that close agreement exists between the theoretical sensor models developed and the experimental results. Further, it is concluded that each sensor has its own unique properties and is thus suited to certain classes of applications.
