Paper Abstract

This paper describes a 35 GHz and 95 GHz instrumentation radar system and the associated data acquisition/processing system developed by the Georgia Tech Research Institute (GTRI). The radar are polarimetric coherent and wide bandwidth providing high range resolution. Polarimetric signatures on the order of 4-6 inches. High cross range imaging equal to or better that the range resolution is generated using inverse synthetic aperture radar processing (ISAR). In addition to systems development data calibration procedures have been developed which provide the needed quality of data to support the development and evaluation of more complex processing concepts (e.g. image processing, polarimetric processing). The key parameters of the radar units are listed in table 1.

The paper will describe the design of the radar units as well as the overall function of the data acquisition and processing software. Radar performance data will be presented which will demonstrate the effectiveness of the various calibration techniques. Data examples will include RCS polar plots, high range resolution profiles, and ISAR plots with and without correction of system errors.
