Abstract : The effects of superdirective design on antenna gain and angle accuracy have been investigated. Numerical results indicate that modest improvements in directivity are possible with concurrent gain improvements. The characteristics of phase patterns have also been investigated; these patterns have constant amplitude but wide spatial bandwidth and are important for angular dispersion-compression applications. Factors affecting the maximum likelihood estimates of angular parameters have been studied. Both angle and angle-rate measurements are considered for wideband and narrowband cases. Correlation principles for both electronically and mechanically scanned patterns are reviewed and two new pattern processing concepts are described. (Author)
