Performance Enhancement of the NPS Transient Electromagnetic Scattering Laboratory

Abstract

This thesis describes the performance enhancement of the NPS transient Electromagnetic Scattering Laboratory (TESL) accomplished by replacing the old HP 8349A microwave preamplifier of the dual amplifier configuration with a new Avantek 13533-5-13 GHz amplifier and optimizing the delay line length for the 1-6 GHz amplifier. New Matlab software was developed to process the signals scattered from canonical and complex targets. This software includes a program to calculate the correct delay line length for either amplifier in future modifications. The updated TESL is shown to provide measurements yielding excellent agreement with theoretically predicted responses of canonical targets demonstrating a significant improvement of the signal to noise ratio as compared with the previous configuration. A target library was created to support research in radar target identification based on natural resonances.
