Open System Design and Evolutionary Acquisition Application To The National Missile Defense Family of Radars

摘要

The traditional acquisition process is complex and lengthy. The process does not allow appropriate user interaction/feedback and often, due to its extended period of performance, continuity in program office personnel is lost. Developments usually experience schedule slips and cost over runs. Traditional acquisitions usually develop closed (stove piped) systems employing 'custom' component with 'tightly coupled' software and hardware. The developments lack open system architectures and have minimal commonality, standard interfaces, and protocols. The systems when fielded, usually, are outdated and become obsolete. They are difficult to operate and frequently are surpassed by current technology. They do not easily allow state-of-the-art technology insertion and use of the latest Commercial- Off-The-Shelf (COTS) equipment. Progressively, they become more expensive to maintain. Acquisition reforms have introduced new innovative approaches to systems procurements. Open System (OS) design methodology and the Evolutionary Acquisition (EA) implementation of the spiral process offer a framework for achieving a shorter acquisition timeline, ability to leverage COTS, improve weapon systems performance, allow technology 'refresh', and lowers the overall life cycle costs. Federally Funded Research & Development Centers (FFRDCs) have used an open system approach in their radar developments. Transitioning their technology design methodology to industry will reduce acquisition and life cycle costs. More importantly, it would allow leveraging of industry's rapid advances in commercial technological development. It will also facilitate system upgrades to keep up with the evolving threats.
