Optimum Radiation of Short-Time Duration Signals

摘要

This research was conducted at the University of Massachusetts from 1 April 1985 through 30 September 1988 under the direction of Principal Investigator Daniel H. Schaubert and Co-Principal Investigators David M. Pozar and Robert E. McIntosh. The studies focused on the use of an analytical optimization technique in the frequency domain in order to maximize the signal strength or energy of a short-time-duration pulse that is radiated or received by an antenna. Several canonical problems have been solved in an attempt to elucidate the applications and limitations of the technique and to better understand the underlying principles. The results of the studies have been described in six journal articles and two conference papers and are summarized in this report. The six topics summarized are; energy maximization of radiation from dipole arrays, K-pulse techniques for short-pulse radiation, bounds on antenna response, target discrimination, load synthesis for control of antenna radiation, and experimental studies.
