Abstract
The STEAMR instrument is a Swedish national
contribution to the ESA PREMIER mission, which is a candidate
for the upcoming Earth Core Explorer mission. The STEAMR
instrument is envisaged as a multi-beam limb sounding satellite,
which will utilise 14 simultaneously observing beams in two 12
GHz wide bands from 323 to 357 GHz. To maximize spatial
sampling in the elevation direction the observing beams have
an elliptical geometry, which defines the incoming beams as
being astigmatic. In this paper we present an antenna optics
scheme which corrects for this inherent astigmatism, thereby
ensuring optimum imaging of the incoming to the circularly
symmetric receiver feed horns. Furthermore, the design, synthesis
and electromagnetic verification of a prototype focal plane array
for the STEAMR instrument is also reported.
