无论是河流泛滥还是沿海风暴潮造成的洪水泛滥程度，都需要迅速得到：（a）以便能够规划紧急救济和维修通信和服务;（B）制作河流洪水风险图。不幸的是，就其性质而言，大多数洪水发生在恶劣天气中，这可能严重限制飞机的使用，而广泛的云层覆盖使大多数依赖于光学波长传感器的地球观测卫星无法使用。
合成孔径雷达可以穿透云层，使受影响的地区成像，无论云层覆盖或光线条件如何。本文比较了卫星获取的数据，河流洪水与摄影记录从一个轻型飞机，以证明该技术的准确性。
The extent of floodwater inundation, whether caused by river flooding or coastal storm surges, is required quickly (a) to enable the planning of emergency relief and repairs to communications and services, and (b) for the production of river flood risk maps. Unfortunately, by their nature, most floods occur in bad weather, which can severely restrict the use of aircraft, and extensive cloud cover precludes the use of most earth observing satellites which rely on sensors operating at optical wavelengths.
Synthetic aperture radar, which can penetrate clouds, allows affected areas to be imaged, regardless of cloud cover or light conditions. This paper compares satellite acquired data of river flooding with photographic records obtained from a light aircraft to demonstrate the accuracy of the technique.
