Abstract
Based on the phase difference DF method by using double-base array in a one-dimensional direction,the Doppler shift phase difference formula with higher accuracy is obtained.By using differential and multichannel phase difference detection method for phase-difference rate calculation on airborne platform,the Doppler rate formula based on phase difference measuring is derived.The most important feature of the Doppler rate detection method based on short baseline phase difference measuring is that the Doppler rate can be detected in time.Theoretical analysis shows that the measuring error in Doppler rate detecting can be controlled within a few hertz as long as the baseline is long enough.关键词
