Abstract
The Precision Expandable Radar Calibration Sphere (PERCS) is newly designed for high frequency (HF) radar calibration satellite. There is potential for the PERCS to operate for the C-Band radar calibration. The wire frame structure has several advantages over traditional calibration satellites. This paper aims to realize the inverse synthetic aperture radar (ISAR) imaging for PERCS at C-Band. The bidirectional analytic ray tracing (BART) method is employed to fast calculate the backscattering fields from PERCS. Two-dimensional ISAR imaging of the V180 model are simulated for full polarizations. The imaging results agree with the geometrical structure of the sphere, which may be promising in radar calibration satellite design.
