Method of Moment Simulation of full Arctic Weather Satellite Structure

The Arctic Weather Satellite is a single payload prototype for a meteorological constellation of SmallSats called EPS-Sterna. Previous analysis showed that the Arctic Weather Satellite radiometer suffers from significant spillover in the 54 GHz band. To accurately model the scattering of the spillover, new analysis using method of moments was conducted including the structure of the instrument. This paper details the results of these simulations and the resulting mitigation of the spillover.
