doppler width
解釋
多普勒寬度-
The estimation of frequency offset is based on pilot symbols and non - pilot symbols. this paper also discusses some parameters in the method and gives the way of compensation. to get the estimation method of doppler spread width, we model the rayleigh channel based on the conclusion of gans ’ spectrum analysis based on clarke model
其中頻偏估計採用一種基於導頻符號和去極性非導頻符的方法進行估計，並通過試驗環境驗證了此方法，並確定了這個方法中的參數的取值，在此基礎上介紹了本系統中的頻偏補償方法。 -
The calculated results show that the generation of inversionless gain in doppler - broadened media for a probe field wavelength in much excess of coupling field wavelength is possible, although the coupling field rabi frequency is significantly less than the doppler width
計算表明：在探測場波長遠大於耦合場波長情況下，雖然耦合光的拉比頻率遠小於多普勒加寬，但是無反轉增益依舊存在，而且強于匹配能級的增益。 -
A chirp - z transform ( czt ) algorithm on the which is similar to range - doppler algorithm is studied, and the effective swath width is analyzed. secondly, a modified block czt algorithm is presented, which improvs the computational efficiency of the high - resolution sar imaging with wide swath
