This thesis presents two algorithms for the real-time circuit optimization necessary in spectrally agile radars: a modified gradient search algorithm for application to a high-power, evanescent-mode cavity tuner that uses previous results to improve reconfiguration time and a modified gradient search algorithm compatible with spectrally notched waveforms.
