摘要：

External calibration experiments using active radar calibrator (ARC) were conducted for. the calibration of the Precipitation Radar (PR) of the Tropical Rainfall Measuring Mission (TRMM) satellite from 1998 to 2001. Three modes of ARC operation are used for the experiment: ARC transmitter mode for receiver system of PR, ARC receiver mode for transmitter of PR, and transponder mode for overall system of PR. The experiments were conducted several times a year. The results of the experiments show that the performance of the PR is close to the prelaunch performance and that PR has been working stably for four years.
