Development of Ku-band FM-CW/Pulse-Compression radar for rain observation on a slant-path
Abstract
A Ku-band FM-CW/Pulse-Compression radar was developed at the Kashima Space Research Center in order to evaluate the performance of FM-CW and Pulse-Compression radars for rain observation and further to utilize this system to the study of microwave remote sensing of rain on a slant-path. With this radar, the radar signal can be transmitted from the same antenna installed for propagation data acquisition such as 11.7-GHz BSE beacon signal and 12.0-GHz sky noise temperature. This configuration allows the close comparison of radar with the propagation data without errors due to spatial discrepancy between observing volumes. This paper describes: (1) the design and characteristics of the radar and (2) method and result of radar calibration. Through the calibration, radar sensitivity was verified to be almost equal to that anticipated from the design.
