The application of Howells-Applebaum adaptive control theory tocontinuously variable time-domain reflector antenna response

The mathematical analysis appropriate for evaluating the interference cancellation performance of continuously variable time-domain adaptive antennas is developed. The analysis is applicable to reflector antennas having N auxiliary, continuously variable time delay taps for the case of phase modulated interference. The analysis allows the evaluation of improvement in performance of reflector antennas with variable time delay taps versus fixed delay taps
