This dataset contains circular synthetic aperture radar system captured data for a 5 km diameter area over 31 orbits.
For this challenge problem and dataset, the phase history for 56 targets was extracted from the larger data set and includes 33 civilian vehicles of which many are repeated models, facilitating training and classification experiments. The remaining targets include an open area and 22 reflectors for scattering and calibration research. The circular synthetic aperture radar provides 360 degrees of azimuth around each target. For increased elevation content, the collection contains two nine-orbit volumetric series,where the sensor reduces altitude between each orbit.
The DVD contains data, documentation, and utilities.
