Nonlinear Solutions Inc. (NSI) (formerly known as Rekenthaler Technology Associates Corp) has supported the defense and intelligence communities with a number of studies and analyses of significant national problems, focusing on the cutting-edge of technology. In addition to its primary focus on signal and imaging processing problems, NSI's technical experience has included acoustic and nonacoustic antisubmarine warfare, the use of airborne and space-based synthetic aperture radar (SAR) for automatic discrimination of strategic relocatable targets, design of a tactical situation display (imagery, cartographic data, intelligence information) system for use on board tactical aircraft, nonlinear dynamics (chaotic signal/image processing theory and applications), AEGIS simulator work station design, space sensor system/mobile target simulations, and use of Fourier/frequency domain and other advanced signal processing techniques for automatic feature/target extraction (AFE) using overhead electro-optical (EO), infrared (IR), and SAR imagery. NSI's analytical experience, which covers many of the subject areas important for analysis of force structure and modernization planning issues, runs from identification and evaluation of U.S. and foreign scientific and technical developments -- based primarily on analyses of open scientific publications -- to assessment of Cold War Era Soviet plans and preparation for the use of military force. This overlap between "technical" and "analytical" efforts is intentional: NSI actively employs its intelligence analysis capabilities in support of its S&T efforts, and its S&T expertise in support of its analytical efforts.
