MMW radar cross section range characterizes targets

Examples of high-resolution millimeter-wave radar images of radar targets and the facilities, equipment, and techniques required to obtain these images are presented. Unique inverse synthetic-aperture radar (ISAR), fully polarimetric data collected on the Georgia Tech Research Institute (GTRI) Electromagnetic Test Facility (EMTF) are discussed. An overview is given of the EMTF, which includes a lookdown target radar cross section (RCS) measurement range that comprises: a very stable 100-foot tower with associated elevatable radar platform; a 100-ton-capacity target turntable located 150 ft from the base of the tower; several measurement radars covering the microwave and millimeter-wave (MMW) spectrum; and a target data processing facility.<
