Near-space wind temperature remote sensing technology is an important method to study the dynamics and thermodynamic characteristics of the atmosphere， and a necessary way to improve the accuracy of space weather numerical prediction. According to the remote sensing detection requirements of atmospheric wind temperature in the near space， by analyzing the detection principles and methods of the near space wind field and temperature， and comparing the existing spaceborne passive wind temperature detection methods，a near-infrared spaceborne wind temperature imaging interferometer based on the field-stretched Michelson interferometer is proposed. Its working wavelength is the spectral line of O2 molecules at 1.27 μm， and the detection range covers the entire adjacent space. The working principle and design process of the system are discussed in this paper. The design of Michelson interferometer with field broadening， chromatic aberration correction， and temperature compensation functions and the F-P for frequency discrimination of O2 molecular lines are mainly discussed， and simulation experiments are performed. The simulation results show that the wind speed measurement error is 18.98%， which can meet the detection requirements of the atmospheric wind field and temperature field in the adjacent space.
