Description

technical field [0001] The invention relates to the technical field of radar detection, in particular to a weather radar blind-filling and smoothing processing system and a method thereof. Background technique [0002] Weather radar is a kind of meteorological radar. It is the main tool for monitoring and early warning of strong convective weather. Its working principle is to obtain precipitation by emitting a series of pulsed electromagnetic waves and using the scattering effect of precipitation particles such as clouds, fog, rain, and snow on electromagnetic waves. The spatial location, strength distribution, vertical structure, etc. Radar can effectively monitor the occurrence and development of catastrophic weather such as heavy rain, hail, and tornado; at the same time, it has good performance in quantitatively measuring echo intensity, and can quantitatively estimate precipitation in a wide range; realize fixed-point, quantitative, and timing-based precipitation foreca...

AI Technical Summary

Problems solved by technology

In the application of weather radar, in the past, radar detections used high pulse power and narrow pulses to obtain good range resolution throughout the whole process. When the all-solid-state radar system is adopted, the pulse power of the radar is greatly reduced. To improve the detection capability, it is necessary It is realized by using a large time width. The use of this technology will bring about the detection blind area of ​​the radar. In order to obtain the full-scale detection data, it is necessary to use the blind supplement technology. There will be a large detection intensity gradient at the blind connection, which will affect the detection and identification of weather echoes in the blinding area
