This thesis describes the development of a parallel GaAs FET amplifier configuration for the Transient Electromagnetic Scattering Range at the Naval Postgraduate School. The implementation of the parallel amplifier configuration improved the bandwidth and the signal-to-noise ratio of the range. Existing software was used to process signals scattered from canonical targets. When interpreted, this data was used to optimize the new amplifier configuration. The upgraded facility is shown to provide measurements having excellent agreement with theoretically predicted signatures of simple canonical shapes. A significant improvement of the signal-to-noise ratio and bandwidth of scattered signature vis-a-vis that of the previous laboratory configuration is observed. Results are documented for a target library created to facilitate research into a number of scattering problems. Keywords Radar cross section Transient scattering Signature.
