The utility model provides a double-view-field Doppler heterodyne interferometer, which aims to simultaneously detect Doppler frequency shift information of spectra of two azimuth angle targets which are vertical to each other. The double-view-field Doppler heterodyne interferometer comprises two planar reflectors which are arranged in a manner of facing toward a vertical field of view, the two planar reflectors are vertically staggered to divide a pupil into upper and lower half regions, and an included angle between two straight lines of horizontal projections of the two planar reflectors is 45 degrees; a Koesters prism, a view-field enlarging prism, a diffraction grating, an imaging optical system and an area array detector are sequentially arranged behind the two planar reflectors along a light path; an din the Koesters prism, a short right-angle surface of the two right-angled prisms, which respectively have a 30-degree corner and a 60-degree corner and are spliced together, faces toward the view-field enlarging prism, a hypotenuse side surface of one right-angled prism faces toward the two planar reflectors, and an included angle between the reflecting surface of each planar reflector and the hypotenuse side surface is 67.5 degrees.
