Abstract

A new technique is described that is applicable to the synthesis of large aperture antennas for directed energy and conventional applications. The two principal technical components of this new approach are (1) the extensive application of digital techniques to control and to provide customized waveform synthesis at each transmitting element in the array and (2) the use of a transponding scheme via an RF link to calibrate individual elements and to cohere the entire array. The approach utilizes all-digital electronics except for the analog transponder receiver and power output amplifiers. The transponding RF link avoids the need for providing coaxial cabling to possibly thousands of individual antenna elements in a large two-dimensional aperture.
