Development of the calibration method for the multi-channel sea–tide measurement radar

We studied the calibration method for the sea-tide level multi-channel measurement radar. The sea-tide level is estimated by the increment rate of the phase in each channel. Calibration data were measured directly in the lab and applied to raw radar data. Calibrated data were confirmed to be used to estimate the target height. Drawing on the calibration data analysis, we estimated our height measurement to have a 6.5 cm resolution.
