Digital array radar for Ballistic Missile Defense and Counter-stealth systems analysis and parameter tradeoff study
MetadataShow full item record
United States Navy (USN) sources indicate a need for long-range shipboard radar for the Ballistic Missile Defense (BMD) program to augment and expand the USN's current capabilities. The Naval Postgraduate School (NPS) conducted a study on radar architecture research based on a digital Opportunistic Array (OA) integrated into a ship's hull. Our completed research defined the operational and technical requirements for the system, called the Digital Array Radar for BMD and Counter-stealth (DARBC). Initial analysis included characterization of the threat and definition of the Concept of Operations (CONOPS). Basic operational Key Performance Parameters (KPPs) were defined. Based on a notional ballistic missile Radar Cross Section (RCS), a radar technical parameters study derived the technical requirements for the radar necessary to meet the KPPs. Related research topics included radar parameter sensitivity, cooling, search pattern options, Electronic Attack (EA), ship flexure, topside array layout, supportability, and cost. Finally, reaction time modeling was conducted to quantify the increase in search volume and decision making time using the DARBC.
