1. A method of Doppler imaging, comprising: collecting, by a Doppler imager, a first sample of radiation from a scene through a first field of view; directing the first sample of radiation from the scene into an etalon of the Doppler imager; moving the Doppler imager from a first location to a second location in an orbit around the Earth; collecting, by the Doppler imager, a second sample of radiation from the scene through a second field of view; directing the second sample of radiation from the scene into the etalon of the Doppler imager; and determining one or more conditions of the scene from an image formed by the first or second samples of radiation from the scene that passed through the etalon; wherein collecting the first sample of radiation from the scene through the first field of view further comprises collecting the radiation from a first aperture along a first direction, wherein collecting the second sample of radiation from the scene through the second field of view further comprises collecting the radiation from a second aperture along a second direction, wherein the first direction is non-parallel with the second direction.
