Abstract

The present invention relates to one kind of small integral structure system of ground microwave radiation-scattering meter. The system is integral one of microwave radiation meter and microwave scattering meter, and features the microwave scattering meter of noise system with frequency band range designed to match that of the microwave radiation meter. Under the control of one main controlling and data processing unit, the microwave radiation meter and the microwave scattering meter operate alternately in time sharing mode, have emission leakage detection and receiving gain regulation, and share one receiver. The present invention is favorable to system integration and minimization, and has simplified system structure and lowered system cost.

Description

technical field [0001] The invention relates to a microwave remote sensing instrument, in particular to an integrated miniaturized structure system of a ground microwave radiation-scatterometer. Background technique [0002] Microwave remote sensing has the advantage of working around the clock, and is an important technical means for obtaining remote sensing information. Microwave radiometer is the main instrument for passive microwave remote sensing, and microwave scatterometer is one of the main instruments for active microwave remote sensing. The fusion of active and passive microwave remote sensing has been proved by many experiments that more meaningful and more remote sensing information can be obtained than single active or passive remote sensing. Integrating the microwave radiometer and scatterometer in the same system not only enables simultaneous measurement of active and passive microwave remote sensing, but also provides an equipment platform for fusion process...
