| Research Abstract |
System study of the spaceborne multi-parameter precipitation observation system is performed. The system utilizes a mechanical scan type offset parabolic antenna in which a single parabolic dish is commonly shared by three radio frequencies, and is composed of the combined rain radar/microwave radiometer (13.6 GHz, 35.5 GHz) and cloud radar (94GHz) to observe rain and cloud simultaneously. A Jerusalem Cross type frequency selective surface is examined to commonly share the single dish of the offset parabolic antenna by the three frequencies. The simulation experiment to observe precipitation by the system is also performed.
