The impact of atmospheric background radiation on imaging quality in Doppler Asymmetric Spatial Heterodyne (DASH) interferometers for wind field detection is investigated, and a stray light suppression structure is designed. Utilizing orbital parameters and observation geometry, the influence of atmospheric background radiation on the signal-to-noise ratio (SNR) at varying altitudes is analyzed. Subsequently, a baffle is designed considering system parameters and SNR variation patterns, with its suppression efficacy evaluated via point source transmittance (PST). Results demonstrate that atmospheric background radiation intensifies with decreasing altitude, leading to progressive SNR degradation. PST curves indicate stable in-field PST unaffected by the baffle, preserving target light detection capability. Out-of-field PST decreases with increasing off-axis angle, dropping below 10−8 near the critical stray light suppression angle of 1.07°. The proposed suppression design fulfills system requirements for atmospheric background radiation mitigation.
