A -- NON-LINEAR DYNAMICS, CHAOS AND FRACTALS SOL 95XR099 DUE 050195 POC (RDPC) Harold Smith, AMSMI-RD-PC-HA, Contracting Officer, 205/876- 0908, Synopsis Number R099-95. The Department of the Army is seeking ideas from academia and industry on the potential application of the emerging field of non-linear dynamics, chaos and fractals to improved effectiveness of Army missile systems through programs of cooperative research with academia, industry, and government. The decline in the military budget requires that all alternatives be explored for pooling resources in achieving national defense objectives. The arrival of new ways of visualizing computer data has led to the emergence of new fields of multidisciplinary mathematical theory such as non-linear dynamics, chaos and fractals that are being applied in a number of areas of research in the Research, Development, and Engineering Center (RDEC) at Redstone Arsenal, AL. Among the areas of investigation are: the development of a fractal Brownian motion infrared radiance map with spatial correlation properties closely matching that of measured data for use in closed-loop simulation of missile systems; the application of fractal geometry to the problem of discriminating targets from background in the millimeter wave region; the application of fractal analsis to multispectral imagery and automatic target recognition imagery; the application of fractals to the generation of synthetic scenes for application in closed loop, real time simulation of missile systems; the application of chaos and fractals to both the encryption and compression of missile guidance data; and, the application of various chaos control algorithms to the selective operation of semiconductor laser arrays operating at high gain and the application of fast training neural networks to adaptive global control of temporal and spatio-temporal chaotic systems. A laboratory test bed is underway to implement simulations on the last topic. Potential coupling of chaos and fractals with the evolutionary trend in multispectral sensing may offer potential enhancements in missile systems for all combat capability categories that may include: (a) improving target acquisition; (b) hardening the seeker against countermeasures; (c) improving target aimpoint selection; (d) enhancing the capability to attack low signature targets; (e) reducing the the logistics burden; (f) enhancing air defense suppression capabilities. The potential for providing multimission capability is also to be sought, and the possibility of exploiting the concept of horizontal technology integration explored. Through these efforts in cooperative research, the RDEC seeks to (a) develop interservice and international partnerships; (b) leverage industry IR&D program; (c) capitalize on available commercial technology where feasible; (d) exploit the multimission capabilities and the concept or horizontal technology integration; and (e) be alert to the potential of technology insertion opportunities. Cooperative Research and Development Agreements (CRDAs) and Bailment Agreements are two mechanisms through which government and industry may engage in cooperative research. Entering into such agreements does not imply that future contracting opportunities will be available, however. The extensive resources that the RDEC can bring to such a partnership in research includes a top flight scientific and engineering technical staff with research experience in non-linear dynamics, chaos and fractals and chaos control; a wide range of laboratory and field test facilities that may be utilized in this research.
