The Processing Method of the Weather Radar Blind Compensation Smoothing System

Abstract

The invention relates to a weather radar blind-filling and smoothing processing system, a weather radar signal processor, a radar wave generating system, a timing control system for a complete radar machine, and a terminal. Also disclosed is a processing method for an antenna radar blind complement smoothing processing system. The steps are: S1, preset a radar detection range, and the terminal calculates a wide pulse parameter by using a radar equation according to parameters obtained by radar detection; S2, in the preset detection range, for The range that can be detected by the radar determines the detection capability of the connection point, that is, the first smoothing process; S3. In the preset detection range, for the undetected blind area, according to the pulse width set in step S2, calculate the blind connection point detection capability, that is, the second smoothing process. The invention achieves the beneficial effects that the detection capability difference between the wide and narrow pulses at the blind-filling connection distance is not greater than 1 dBZ, the echo gradient is smooth and effective for detecting the blind area, and the problem of the echo gradient abrupt change is solved.

Description

technical field [0001] The invention relates to the technical field of radar detection, in particular to a processing method of a weather radar blind-filling and smoothing processing system. 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 fore...

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
