Embodiment Construction

[0046]In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0047] The wind profiling radar system is a kind of wind measuring radar system. The detection ability of the wind profiling radar system is mainly reflected in the maximum acquisition ability of high-altitude wind, that is, the wind profiling radar system is mainly used to detect atmospheric turbulent motion. When the detection object of the ...

Abstract

The invention provides a processing method and a processing device for a wind profile radar echo signal. The method comprises the following steps: acquiring the wind profile radar echo signal of whichgain is amplified through wind profile radar echo signal processing, wherein the wind profile radar echo signal comprises a meteorological signal and a noise signal; obtaining power of a signal unitaccording to the noise signal in the wind profile radar echo signal; and according to the meteorological signal and the power of the signal unit, obtaining power spectrum distribution of the meteorological signal. The processing method and the processing device for the wind profile radar echo signal, provided by the invention, can accurately describe signal intensity detected by a wind profile radar system, and enable the signal intensity detected by the wind profile radar systems of different models and / or different detection modes to have a consistent processing result.

Description

technical field [0001] The invention relates to radar technology, in particular to a method and device for processing wind profile radar echo signals. Background technique [0002] The wind profiling radar system is a kind of wind measuring radar system. The detection ability of the wind profiling radar system is mainly reflected in the maximum acquisition ability of high-altitude wind, that is, the wind profiling radar system is mainly used to detect atmospheric turbulent motion. When the detection object of the wind profiler radar system is cloud and rain particles, the Rayleigh scattering signal of cloud and rain particles is greater than the turbulence scattering signal. Radar echo signal to determine the strength of the precipitation echo. [0003] In the prior art, different models and / or wind profiler radar systems determine precipitation echo strength in different ways based on wind profiler radar echo signals. Therefore, for the same geographic location, different ...
