Paper Abstract

In an effort to effectively understand signature verification requirements through the variability of a structure's RCS characteristics, the U.S. Army National Ground Intelligence Center (NGIC), with technical support from STL, originated a signature project plan to obtain MMW signatures from multiple similar tanks. In implementing this plan NGIC/STL directed and sponsored turntable measurements performed by the U.S. Army Research Laboratory Sensors and Electromagnetic Resource Directorate on eleven T-72 tanks using an HRR full-polarimetric Ka-band radar. The physical condition and configuration of these vehicles were documented by careful inspection and then photographed during the acquisition sequence at 45 degree(s) azimuth intervals. The turntable signature of one vehicle was acquired eight times over the three day signatures acquisition period for establishing measurement variability on any single target. At several intervals between target measurements, the turntable signature of a 30 m2 trihedral was also acquired as a calibration reference for the signature library. Through an RCS goodness-of-fit correlation and ISAR comparison study, the signature-to-signature variability was evaluated for the eighteen HRR turntable measurements of the T-72 tanks. This signature data is available from NGIC on request for Government Agencies and Government Contractors with an established need-to-know.
