G. A. Tyler Associates, Inc. — Department of Defense STTR Phase I: ABSTRACT: A design analysis is proposed to enhance the performance of conventional phased

Description

ABSTRACT: A design analysis is proposed to enhance the performance of conventional phased array weapon systems and ensure that traditionally required pointing and tracking functions can be maintained. A key feature of the proposed program is the inclusion of complimentary technologies that mitigate the limitations of existing concepts under consideration that are significantly degraded by speckle. These technologies include an assessment of the utility of laser guide stars for atmospheric compensation, consideration of a system to enhance phasing performance and exploitation of the speckle return synthetic aperture which is almost twice the diameter of the array to perform the fine track function. BENEFIT: The proposed work will develop an optical phased array with several innovations that address critical problems. A novel combination of a conventional camera and a speckle imaging technique addresses the problems of acquisition, pointing, and tracking. This and other innovations combine to form a phased array system suitable for use as a directed energy weapon in several roles. The system can be easily adapted for a variety of roles, including the gunship (AC-130) and mobile air defense roles. Potential uses also exist in other uses of directed energy, such as medicine and industrial welding.
