| 摘 要： | 对RTK高程和Heave信号在合成之前进行了预处理，确保了短周期内两者监测尺度和时间上的一致；然后利用数字信号处理技术实现这两个信号的融合；并通过一个实验对信号合成方法的精度进行了全面的分析和评估，认为该方法可以达到约6～7cm的精度，将传统多波束数据处理方法的精度提高了1倍。 |

| Abstract: | In order to eliminate the shortcomings of traditional methods in multibeam data processing,a kind of new method,which is based on the blend of RTK height signal and heave signal,is presented.Three kinds of methods,which are used for blending the two signals,are researched.They are constrained blend method,signal-processing method with Butterworth filter and FFT spectrum analysis method respectively.For the former two kinds of methods,they can not meet with the requirements of strict time synochronization and maximum magnitide respond in signal processing,thus,FFT spectrum analysis technology is finally introduced,which overcomes the shortcomings of the other two kinds of methods.Finally,the accuracy of signal blending method is discussed with a complicated multibeam surveying experiment.An all-around analysis is done.The below results can be obtained through analysis,comparison and calculation.The signal blending method can achieve standard deviation about 6 cm,and can meet with the requirement of precise projects underwater monitoring seabed/riverbed. |
