Abstract:
The Fengyun3 rain measurement (FY3 RM) satellite will be used to observe strong precipitation like typhoon and so on, and also to observe other precipitation over the low and medium latitude areas. The accurate 3dimension structure of the precipitation will be achieved by its core payload, the dualfrequency precipitation measurement radar (PMR). The main performance characteristics of PMR for the application including the range resolution, horizontal resolution, scan angle, antenna sidelobe, measurement accuracy and beam matching accuracy are analyzed by simulation. The analysis results show that the PMR has the same precipitation measuring capability as the Global Precipitation Measurement dualfrequency precipitation radar. In order to validate the function of PMR, some flight experiments were carried out by its airborne proto in 2010The capability of detecting precipitation of the protoradar is analyzed using the data achieved during the experiments, and the functions and the main performance characteristics of PMR are also validated.
