Interference Suppression Studies. Studies of Antenna Side-Lobe Reduction

摘要

This work is divided into two parts: A theoretical study and a discussion of actual applications. In the first part, a brief introduction of the common antenna synthesis procedures is presented. Two new novel approaches were also suggested. First, the use of the signal-to-noise ratio as a criterion of design of arrays. Second, the use of the prolate spheroidal functions for aperture synthesis. In the second part, a number of high performance antennas as well as experimental work performed in the University of Pennsylvania is discussed. Practical techniques, such as tunneling application of microwave absorbing material, are described and evaluated. (Author)
