  1. Real-Time Geo-Registration on High-Performance Computers Thomas Kurien Luke Cico Mercury Computer Systems, Inc. Alan Chao Monica Burke ALPHATECH, Inc. High Performance Embedded Computing Workshop - September 24, 2002

  2. SAR Image Geo-Registration Desired Capabilities and Constraints Ground Station SAR Collection Platforms Processing Processing Dissemination Processing (Sensor) Tasking Processing Exploitation Command Centers Massed Forces High-Value Targets • Objective: prosecute time-critical targets in dynamic battlespace • Requirement: near real-time mensuration and geo-location of targets in collected SAR image • Satisfy space, weight, and power constraints (airborne sensor platforms, mobile ground stations)

  3. Scalable Geo-Registration Algorithm:Demo Interface Scalability Results Number of Processors Test Image Metadata Test Image

  4. Computational Scalability • Implementation demonstrates close to linear scalability • For 64-processor system: ~ 2.2 seconds (estimated)
