Jam Resistant Communications Systems Techniques
Abstract
The objective of this effort was to develop techniques to increase the jam resistant capability of communication systems. The effort involved the assessment of the limitations, both theoretical and practical, that restrict the effectiveness of adaptive arrays operating in various environments, and wherever possible to overcome these limitations by appropriate design changes. A technique was developed to predict adaptive array performance and provide guidelines for the design of adaptive arrays on complex structures to produce specified performance levels. A cascaded adaptive array consisting of a power inversion stage followed by an LMS stage has been designed, built and tested showing improved dynamic range performances. An angle of arrival estimation system capable of providing accurate angle estimates in the presence of multiple high powered jammers has been developed. The angle of arrival estimate could be utilized to provide pointing information in a demand assignment TDMA SATCOM system employing high gain switchable downlink beams.
