Abstract:Since the Doppler shifts of airglow orauroralemission lines due to neutral winds are extremely small, it is essential to determine the center position and radius of fringes with the uppermost accuracy. In this paper, a new method is presented for the center position and radius determination of incomplete interference fringes of Fabry-Perot Interferometer (FPI). Due to the data noise comes from FPI instrument and space environment, the data pre-processing was firstly carried out including mean filtering and wie… Show more
