摘要

An analysis of target separability has been performed under an OSD Target Management Initiative program entitled Radar Variations. The program has concentrated on analyzing radar signatures from multiple main battle tanks(MBTs) in order to quantify the differences in Ka-band signatures of vehicles due to intraclass and interclass target variations. As a significant factor in the success of the Radar Variations program, U Mass Lowell's Submillimeter-Wave Technology Laboratory (STL) and U.S. Army National Ground Intelligence Center (NGIC) fabricated 1/16th scale "exact" replicas of the vehicles used in the Ka-band radar signature acquisition study directed by Simulation Technologies, Inc. (SimTech) and Targets Management Office (TMO). These replicas enabled NGIC to measure statistically significant amounts of high-fidelity signature data for a variety of target configurations with an indoor compact radar range. The metrics and model building procedures now provide the foundation for executing an analysis of target structures in operational environments. Multiple levels of operational environments can be modeled using modular assemblies of troop support hardware with the fine-scale replicas. To exemplify this capability, 4" resolution X-band signatures have been collected on precisely aligned test configured and operationally configured structures for comparative signature studies. Signature sets have been correlated to determine if, or which, in-scene target conditions produce changes in signature content that may confuse automated target recognition (ATR) algorithms. The signature-to-signature variability quantified is presented, along with a description and examples of the signature analysis techniques exploited. This signature data is available from NGIC on request for Government Agencies and Government Contractors with an established need-to-know.
