According to the test platform, the cloud can be observed and imaged with multiple degrees of freedom.

Description

technical field [0001] The invention belongs to the technical field of radar measurement and relates to a radar test platform, in particular to a multi-degree-of-freedom polarization cloud measurement radar test platform. Background technique [0002] Clouds are one of the most important and most difficult meteorological elements in global climate models, which have a significant impact on the Earth's energy balance, climate change, and weather evolution. Clouds control the Earth's energy budget by affecting the sun's short-wave radiation and the Earth's long-wave radiation. Monitoring the distribution, characteristics and evolution of clouds plays a very important role in the study of global climate change and weather forecasting. [0003] The lidar wavelength is too short, and the cloud scattering effect is strong. It can only measure the height of the cloud base or cloud top, but cannot measure the microscopic parameters inside the cloud layer such as the size, concentra...

AI Technical Summary

Problems solved by technology

[0006] (1) Existing terahertz radars cannot perform multi-angle polarization processing when cloud observation and imaging, which results in single data collected when cloud observation and imaging, only presenting a one-dimensional data set, and stereoscopic imaging of data cannot be performed analyze

[0007] (2) The receiving end or transmitting end of the existing terahertz radar is placed in a fixed state. When measuring clouds, it is impossible to meet the requirements of single polarization or combined dual polarization, and the obtained one-dimensional data set is in a linear state. When performing one-dimensional data imaging analysis, there is a certain lack of data set
