Description
As a parabolic antenna revolves, the microwave scanning radiometer (MSR)
continuously scans the earth surface conically for a width of 317 km. During
this process, the MSR receives weak radio waves in the two frequency bands of
23.8 and 31.4 GHz. Its resolution in terms of earth area is 32 km in the 23.8
GHz band and 23 km in the 31.4 GHz band.
