Design and In-Orbit Validation of a Novel Compact Bidirectional Trapezoidal Reflector for X-Band Spaceborne SAR Absolute Radiometric Calibration

Spaceborne synthetic aperture radar (SAR) absolute radiometric calibration relies on point targets with a known radar cross-section (RCS), such as triangular trihedral corner reflectors (TTCRs). Traditionally, radiometric calibration using TTCRs requires precise alignment of the corner reflector (CR...
