ATMS Antenna Beam Analysis Software

摘要

The Advanced Technology Microwave Sounder (ATMS) Antenna Beam Analysis Software uses a suite of test data to calculate the ATMS instrument beam pointing, and secondarily, the polarization state, in the coordinates of the onboard optical cube. The software uses measurement inputs of RF radiation pattern performance made at multiple rotational viewpoints and across a range of frequencies, rotation matrices to characterize physical rotation between the instrument measurement states and the optical cube, and correction rota-tion matrices used to eliminate gravity effects through an independent characterization.
