Abstract
In microwave remote sensing, if we want to acquire active and passive remote sensing information of an object simultaneously, we usually measure it with a scatterometer and a radiometer at the same time. Because two remote sensors are used, the experiment is very complicated. A scattero-radiometer is developed in order to reduce remote sensor cost and experiment difficulty. This scattero- radiometer consists of a continuous wave scatterometer and a digital gain compensation radiometer. In this paper, the block diagram and the timing program of this scattero- radiometer are detailed submitted. Performance test show that the scattero-radiometer not only remains original performance of a scatterometer and a radiometer, but also is able to measure backscattering coefficient and brightness temperature simultaneously. It is more fit for acquiring active and passive microwave remote sensing information simultaneously.
