GRD calibration

Hello, I have this project at university… so i need a GRD Sentinel 1 product but when i download this from copernicus web, was it calibrated? Must it calibrate to ship detection?

GRD, must be calibrated according to the objective, to be calibrated to sigma0 or/and gamma0 Do more post-processing. It depends to the approach of your study.
