Abstract

SAR instruments require careful calibration to ensure the fidelity of the image data. The use of reference targets on the ground as calibration standards is a proven technique. However, for new generations of SAR instruments using new wavelengths with polarimetric and interferometric modes, new calibration techniques need to be considered. Transponders which code the signal received from the SAR before retransmission have the advantages of unambiguous detection and decoupling of the signal from the surrounding targets. The coded transponder technique and its use fro SAR calibration are discussed.
