Abstract

The invention discloses a forming-ring-surface-antenna-based multi-band scanning calibration and radiation detection system comprising a forming ring-surface antenna, a calibration source, a multi-band forming sub reflecting surface array, a multi-band receiver and a feed source array, a scanning mechanism and a support structure, a control power distribution module, a data acquisition and processing module and a platform support structure. According to the invention, the ring-surface antenna is used as a main reflecting surface of the system; the receiving beam directional diagram is controlled based on the forming design of the ring-surface antenna and the sub reflecting surface; the scanning mechanism drives the multi-band receiver and the feed source array as well as the multi-band forming sub reflecting surface array to carry out periodic rotation by fixing the forming ring-surface antenna and the calibration source, so that periodic calibration and scanning detection of the system are realized.

Description

technical field [0001] The invention belongs to the technical field of radiation detection or scanning imaging, in particular to a multi-band scanning calibration and radiation detection system based on a shaped loop antenna. Background technique [0002] The detection of the atmosphere and clouds is the most important data source in meteorological and climate applications, and it is also one of the most difficult meteorological elements to determine. Their high-resolution and high-precision detection can improve climate prediction, numerical weather prediction accuracy, and enhance artificial influence. Weather implementation efficiency and extreme weather prediction capabilities have important applications in many aspects, and are of great significance to meet the growing needs of the military and civilians for climate prediction and weather forecasting. The atmosphere and clouds have rich radiation and scattering spectra in the millimeter-wave and terahertz frequency band...
