The stability and measuring accuracy of the wave sensor are evaluated on the sea in an objective and comprehensive way for the newly developed SZF2-1A multi-parameter wave test buoy. Comparing with the measured data from the MARK Ⅱ wave buoy, it shows that the SZF2-1A buoy and MARK Ⅱ buoy have good consistency. The correlation coefficient of maximum wave height between the two wave buoys is 0.96, and the root mean square error is 0.33 m; the correlation coefficient of significant wave height is 0.99, the root mean square error is 0.13 m, and the relative error is 6.0%; the correlation coefficient of average wave height is 0.98,the root mean square error is 0.088 m, and the relative error is 6.2%. It is proved that the periods measured by the two wave buoys corresponding to significant wave height and average wave height have good consistency, with correlation coefficient being 0.86 and 0.87, respectively. The correlation coefficient of wave direction of the two models is 0.77. It is concluded that the SZF2-1A multi-parameter wave test buoy is stable in operation and the wave sensor on the SZF2-1A buoy is accurate and reliable in its measuring performance.
