星载微波散射计是目前唯一能够同时全天候、全天时、高精度、高分辨率和短周期测量海洋表面风场矢量的有源微波遥感器，这一能力已在美国Seasat-1[1]、欧空局ERS-1/2[1]、日本ADEOS-1/2[1]、中国HY-2等卫星装载的微波散射计上得到了充分的证明。双波段、扇形波束圆锥扫描星载微波散射计是一种具有国际先进水平的星载微波散射计，具有测风范围大、测量精度高的优点。文章简要分析了该微波散射计的工作原理、总体方案设计、关键技术、及初步性能评估等。%Space-borne microwave scatterometer is a unique microwave remote sensor which can provide all weather, all time, and short-period measurement with high precision and high spatial resolution for the ocean surface wind field. Double-band fan-beam conically scanning space-borne microwave scatterometer is an advanced space-borne microwave scatterome-ter, which can be applied in the measurement of large-scale and accurate wind field. This paper describes the principle of operation, system design, core technology, and performance estimation based on the simulation platform for this system.
