摘　　要：本文论述了风云三号卫星B星微波湿度计(MWHS-3B)发射前热真空定标的原理和方法,建立了各种定标误差的修正算法,获得了MWHS-3B的系统线性度、观测不同目标的灵敏度和最终定标精度等关键技术指标。这些参数已经用于MWHS-3B在轨数据的处理。The principle and methods on thermal/vacuum （T/V） testing of microwave humidity sounder （MWHS） on FY-3B satellite were described; correction algorithms on calibration errors were developed, and some main specifications of MWHS-3B, such as linearity, sensitivity and calibration precision, were obtained. The parameters derived from the T/V testing had been used in in-orbit data processing to produce brightness tem- perature products in FY-3B ground system.
