Ground Moving Target Tracking and Exploitation Performance Measures

摘要

Ground Moving Target Indication provides a unique source of information for the exploitation of surface and low flying aircraft at long range, in all weather, providing situation awareness, targeting, and intelligence information. While airborne moving target indication and fire control radars have been around for a long period of time, it has been only the last decade when Ground Moving Target Indication (GMTI) data has been collected and used to prosecute mobile surface targets. This presentation addresses the use of GMTI data from providing intelligence information to the analysis and leads to the challenges associated with doing long-term track maintenance. The intelligence community has been expressing interest in GMTI data since 1999 when investments were made to develop the first exploitation capability that focused on products from Joint STARS GMTI data providing a web based capability to process and exploit Joint STARS data via a Network Centric Architecture. At the same time, DARPA and AFRL were pursuing the Long Term Track Maintenance challenge performing multi- platform command and control, horizontally fusing multiple sensors with weapons for a long-range precision fire control system. The focus of this presentation is to cover performance metrics. The metrics will be associated with operators-in-the-loop evaluations looking at intelligence and analysis for the find, fix, track, and assess portion of the weapon. The second set of metrics focus on long- term track maintenance evaluations. Track accuracy and persistence in time critical targeting, which address the track, target, and engage portion of the weapon chain. Programs to be discussed include the Moving Target Information Exploitation System (MTIX) program with respect to intelligence products, the Multi-Platform Tracking Exploitation (MPTE) and the Affordable Moving Surface Target Engagement (AMSTE) programs with respect to Long Term Track Maintenance and Precision Fire Control.
