Implementation method of solar radiation observation device based on photoelectric principle

Abstract

The invention discloses a telemetry polarization diversity system and accordingly the problems that diversity systems are complicated in structure, difficult to implement, large in limitation and not beneficial to popularization and application in the prior art are mainly solved. The telemetry polarization diversity system comprises a first A / D (Analog to Digital) sampler, a second A / D sampler, a first frequency mixer, a first low pass filter, a second frequency mixer and a second low pass filter; the input end of the first frequency mixer is connected with the first A / D sampler and the output end of the first frequency mixer is connected with a first multi-rate signal processor; the input end of the first low pass filter is connected with the first multi-rate signal processor and the output end of the first low pass filter is connected with a difference mode ring and a common mode ring; the input end of the second frequency mixer is connected with the second A / D sampler and the output end of the second frequency mixer is connected with a second multi-rate signal processor; the input end of the second low pass filter is connected with the second multi-rate signal processor and the output end of the second low pass filter is connected with the difference mode ring and the common mode ring. Accordingly, the structure is simple, the implementation is convenient, the cost performance is high, and the practical value and the popularization value are high.

Description

technical field [0001] The invention relates to a solar radiation observation device, in particular to a solar radiation observation device based on the photoelectric principle and its realization method. Background technique [0002] Solar radiation refers to the electromagnetic wave and particle flow emitted by the sun to space. The radiation observed in meteorological operations includes total radiation, direct radiation, scattered radiation, reflected radiation and net radiation. In meteorological operations, the observation of radiation is mainly realized through pyranometers. Therefore, the performance of the pyranometer and the cost performance are important factors affecting the observation effect. [0003] Currently, pyranometers widely used in meteorological operations mainly have the following defects: [0004] 1. Each pyranometer can only achieve a specific radiation observation; [0005] 2. Each pyranometer is based on the principle of light and heat, and the ...
