TRANSIENT BEHAVIOR OF LARGE ARRAYS.

Abstract

Results are reported of the first phase of a theoretical and experimental investigation into the transient response of microwave components used in feed networks of large antenna array systems. The concepts commonly used in linear lumped network theory are applied to the transient behavior of distributed networks. In particular, it was found that for TEM mode components a network characterization in the complex z-plane enables closed form solutions to be obtained from which the frequency response and transient behavior can be found. Flow graph techniques are applied to the analysis of TEM mode components, such as couplers, ring hybrids, power dividers, phase shifters, etc., and theoretical results for the impulse, step, and modulated step responses as well as the amplitude spectrums and phase functions are presented. Experimental results of tests on UHF and L-band components which verify the theoretical results are presented. The results were obtained by using newly developed techniques for generating pulses of approximately 0.2 nanosecond in duration and high-frequency sampling oscilloscope displays. (Author)
