The method used for the calibration of the ERASME helicopter-borne side-looking C-band radar is described. A global error budget for the radar is established. Data processing is discussed, which allows for antenna pattern correction and for flight parameters correction (pitch, roll, altitude), as an introduction for the calibration procedures: internal calibration, external calibration on corner reflectors for absolute calibration (within 1 dB), and a statistical approach which uses experimental data and analyzes the correlation between processed data and recorded flight parameters. This method provides a way to check or adjust the calibration for specific flight configurations, and makes possible a relative accuracy of better than 0.5 dB for data comparison within the radar swath.
