TRANSIENT BEHAVIOR OF LARGE ARRAYS.
Abstract
Results of the second phase of a theoretical and experimental investigation of the transient behavior of microwave components used in feed networks of large antenna array systems are reported. Various combination networks treated include cascade connections of power dividers, switches, ring hybrids and directional couplers. The major emphasis of this report concerns the transient behavior of commonly used waveguide components. First, the transient response of straight sections of rectangular waveguide is found. The effect of coax-to-waveguide adapters on the transient response of sections of waveguide is considered, and first order approximations are used to estimate settling time for a step-modulated input excitation. These approximate results and the results reported in the first quarterly report are used to establish solutions for the more complicated waveguide components, namely the branch wall coupler and magic tee. Experimental results of the transient behavior of L-band TEM mode combination networks and waveguide structures are presented. Finally, a new technique for the generation of synchronized step-modulated signals at L band is presented.
