IMPROVED ANGULAR RESOLUTION TECHNIQUES.
Abstract
This report describes a study and investigation of the split aperture technique for antenna intrabeam signal processing. This technique makes use of phase and amplitude information received on a number of subapertures of a large aperture antenna, in conjunction with a priori information on the number of targets in the antenna beam, to provide an improvement in angular resolution. A computer simulation is described which estimates the location of the multiple targets as a function of the relative target amplitudes and phases, S/N ratio, position in the beam and system measuring accuracy. Results obtained from an experimental setup to simulate two targets are presented and compared with the calculated results. Suggestions for possible system implementations are given. Section 1 presents a historical development of the problem, Section 2 a theoretical formulation of the split aperture technique, Section 3 the experimental measurements, and Sections 4 and 5 the conclusions and recommendations. The computer programs and signal processing techniques are presented. (Author)
