| Summary: | The payload can be classified as a passive and active type. Generally radar satellite to
acquire specific information through various radar images will use the SAR (Synthetic
Aperture Radar) as active type payload. the principal of SAR satellite is to receive
the signal returned from certain objects and/or surfaces in order to construct an radar
image. The data acquired from the satellite in its real orbit shall be needed to perform
successful CAL/VAL (Calibration & Validation) because the SAR satellite have to
receive the returned signal for SAR image construction. In order to do the above,
the returned signal shall be related to ground targets. Especially ground target is the
corner reflector (CR) for CAL/VAL. Generally the reflector has various types and
shapes. Their selection can be dependent on characteristics and mission objectives of
SAR satellite. In this paper, reflector focused on the optimal case and effective case
has been studied and then the trihedral corner reflector under this study has been
designed and its performance also analyzed. |
