Preliminary aliasing error analysis of a ground-based interferometric radiometry concept for lunar observation

The Moon is an ideal target for cross-calibration of radiometric measurements due to its stable surface geophysical properties. To explore the lunar calibration capability for the spaceborne microwave radiometer missions, a ground-based inter-ferometric radiometry concept for lunar observation is proposed in this paper, the observation model, site environment and array design are discussed. A large antenna spacing design is considered to achieve satisfactory spatial resolution while maintaining a reasonable system size. The resulting aliasing error is evaluated through imaging simulations.
