解釋
快速傅里葉變換技術-
In the first part, the research progress of cloud motion wind is introduced and the significance of the fourier phrase analysis technique was given. in the second part, based on fluctuation theory and fourier phrase analysis, the one - dim fourier analysis technique on cloud motion winds is deduced, and the error of the technique is analyzed. in the third part, basing on the one - dim fourier phrase analysis technique, the two - dim fourier phrase analysis technique is given, and improved the arithmetic of fast fourier transform ( fft )
本文由六章組成,第一章介紹雲導風技術的研究進展和傅立葉導風技術的研究意義;第二章以波動理論和傅立葉變換為基礎,對一維傅立葉相位導風技術進行理論推導和誤差分析;第三章基於一維傅立葉相位法導風,給出二維傅立葉相位法導風的理論分析,並對該演算法進行了改進,加入了快速傅立葉演算法。
