Item Adaptive multiscale estimation for fusing image data(2001) Slatton, Kenneth Clinton; Crawford, Melba M.; Evans, Brian L. (Brian Lawrence), 1965-Item Model-based signal processing for radar imaging of targets with complex motions(2002) Li, Junfei; Ling, HaoItem Optimal configuration of a parallel embedded system for synthetic aperture radar processing(Texas Tech University, 1997-12) Muehring, Jeffrey TEmbedded systems often must adhere to strict size, weight and power (SWAP) constraints and yet provide tremendous computational throughput. Increasing the difficulty of this challenge, there is a trend to utilize commercial-off-the-shelf (COTS) components in the design of such systems to reduce both total cost and time to market. Employment of COTS components also promotes standardization and permits a more generalized approach to system evaluation and design than do systems designed at the application-specific-integrated-circuit (ASIC) level. The computationally intensive application of synthetic aperture radar (SAR) is by nature a high-performance embedded application that lends itself to parallelization. Mercury Computer Systems' RACE multicomputer is the COTS computing platform under investigation. With the target software and hardware defined, a system performance model, in the context of SWAP, is developed based on mathematical programming. This work proposes an optimization technique using a combination of constrained nonlinear and integer programming.
