N2 - The significant wave height (SWH) is one of the most important ocean wave information describing sea state. The high-precision SWH can be extracted using the signal-to-noise ratio (SNR) method based on shore-based X-band radar. However, for ship-borne case, the error of the extracted SWH increases because of the motion of ship-borne radar. In this paper, the effect of ship-borne X-band radar vertical motion on SWH estimation is analyzed in detail. First, radar images of ocean wave are simulated based on linear wave theory. Then, the relationships between the illumination rate and the detection distance at different antenna heights are discussed. Finally, the effect of the vertical motion amplitude of the ship-born radar on the root square of SNR is investigated. Simulation results show that the vertical motion of the ship-borne radar is one of the main reasons for the increasement of SWH estimation error. Furthermore, the root square of SNR and the change rate of the vertical motion amplitude are negatively correlated. This work provides a significant theoretical foundation in future application for ocean remote sensing using ship-borne X-band radar.
