Tidal harmonic analysis
潮汐调和分析方法的探讨

To analyze observational data sampled at non-equal time intervals,we devised a least squares method of tidal harmonic analysis,based on Matlab's function.By this method,the harmonic constants were almost the same with observational data sampled at either equal time intervals or and non-equal time intervals at Dalian and Beihai in 1985.The harmonic analysis with data sampled at different time intervals showed that frequency aliasing occured when the tidal frequency was more than 1/2 of the sampling frequency...
