Optically Linked EHF Antenna Array
Abstract
This report covers the work done under Task 5 of Project 45194263 entitled, 'Communications Adaptive Array Processor Evaluation.' Adaptive antenna technology has been an area of interest for many years. The progress to date can be characterized by extensive research on algorithms and processing architectures, development of a large number of prototype systems and fielding of a few systems. Adaptive antenna systems normally consist of two or more antenna elements, two or more receivers, amplitude and phase weighting networks for one or more elements and a signal combiner. For some applications the size, weight, power consumption and cost or multiple receivers, antenna elements and associated radio frequency (RF) cabling can be limiting factors. In spite of these limitations, the impressive interference cancellation capabilities of adaptive antenna system is highly desirable. Recent advances in photonics technology could provide solutions to the limitations described above. RF modulated lasers, optical cabling and optical detectors could reduce much of the size, weight, power consumption and cost of conventional adaptive array systems. (R.H.)
