Registered Frequency-Stepped Radar Data Collected on a Maneuvering Pickup Truck at Ka-Band

摘要

Two-dimensional inverse synthetic aperture radar (ISAR) imagery can be generated with a stationary radar illuminating a moving target. Data were collected on a 1994 Chevy Cheyenne 1500 series pickup as it was slowly pulled through a stationary radar beam to help analyze noncooperative ISAR algorithms. The speed of the vehicle varied from constant velocity to constant acceleration and the turning angle of the wheels was constant. The radar was a frequency- agile, coherent, pulsed K sub a-band instrumentation radar built by the U.S. Army Research Laboratory (ARL). The data were registered optically and with stationary and rotating reflectors.
