Atmospheric Tomography with a Rotating Mirror Sensor

Ionospheric phenomena have an impact on terrestrial technology, affecting navigation, communication, and radio astronomy, in order to closely study these phenomena, we are developing an ionospheric sounder featuring a rotating lens system. This rotating lens provides multiple views of the same volume of space, which can be used to provide tomographic images of the ionosphere. Tomography is expressed here using the natural pixel representation. Key to this representation is the computation of the elements of the Gram matrix, which is complicated by the ongoing orbital motion and rotation of the sensor. A discussion of the point spread function is presented, followed by some tomographic reconstructions from simulated data
