UNCONVENTIONAL ANTENNA TECHNIQUES FOR IMPROVED AZIMUTH RESOLUTION.
Abstract
Various signal processing techniques for improved angular resolution were investigated during the course of a 4-year study program. These included, initially, product arrays, time-modulated arrays, and arrays using nonreciprocal transmitting-receiving antenna elements. Resolution improvement obtained was limited to 50 percent and often involved severe trade-offs. The angular resolution problem was then formulated in a decision theoretic context, and the theoretical limits of resolution were estimated. Computer simulation studies indicated that resolution of targets as close as a quarter of a 3-db beamwidth was possible with over 90-percent probability. A system based on decision theoretic principles was then designed and implemented. Tests performed on the experimental system verified the computer simulation results. (Author)
