As an advanced device for observing atmospheric winds,the spaceborne Doppler Asymmetric Spatial Heterodyne(DASH)interferometer also encounters challenges associated with phase distortion,par-ticularly in limb sounding *** paper discusses interferogram modeling and phase distortion cor-rection techniques for spaceborne DASH *** modeling of phase distortion interferograms with and without Doppler shift for limb observation was conducted,and the effectiveness of the analytical expression was verified through numerical *** simulation results indicate that errors propagate layer by layer while using the onion-peeling inversion algorithm to handle phase-distorted *** contrast,the phase distortion correction algorithm can achieve effective *** phase correction method can be successfully applied to correct phase distortions in the interferograms of the spaceborne DASH interferometer,providing a feasible solution to enhance its measurement accuracy.
