Each file contains a header followed by phase history data with sufficient aperture and bandwidth to support up to 1 foot x 1 foot range/cross range resolution. Signature data is in raw binary format, where each sample in the phase history matrix is in single precision SUN floating point format. A sample of an ASCII header pre-appended to each file is shown below:
