Robustness of PolSAR CS to Calibration Errors

Dropped-channel polarimetric synthetic aperture radar (PolSAR) compressive sensing (CS) reduces data storage/transmission and receiver hardware requirements by utilising antenna crosstalk and CS techniques to recover dropped channel(s). This paper examines the robustness of dropped-channel PolSAR CS (DCPCS) to calibration errors on the antenna crosstalk matrix. Although the antenna design problem is relaxed to a large region of acceptable crosstalk values, very accurate calibration may be required.
