Characteristic frequency responses of broadband adaptive arrays
John E. Hudson · IEE Proceedings F Communications Radar and Signal Processing · 1983
The interference direction frequency response and cancellation capability of a broadband tapped delay line adaptive array are discussed. The frequency response is found to be an entire function in the s-plane, but the hypothesis is advanced that, for a given total time delay and number of degrees of freedom, it approximates to the rational frequency response function of a single uniformly tapped delay line for band- limited interference spectra. Some elementary expressions for the cancellation are derived.
