All-airspace multi-directional scanning mode-based cloud radar echo three-dimensional display method

Abstract

The invention discloses an all-airspace multi-directional scanning mode-based cloud radar echo three-dimensional display method. The all-airspace multi-directional scanning mode-based cloud radar echothree-dimensional display method comprises the steps of performing quality control processing on echo data of each direction; building a three-dimensional coordinate system, and taking a cloud radarstation as an origin point of the three-dimensional coordinate system, wherein X axis expresses a distance in an east-west direction, Y axis expresses a distance in a north-south direction, and Z axisexpresses height; fabricating a two-dimensional echo image in each direction in the three-dimensional coordinate system; performing texture mapping on a front surface and a back surface of the two-dimension echo image in each direction; and displaying on a three-dimensional display platform. By the all-airspace multi-directional scanning mode-based cloud radar echo three-dimensional display method, the cloud generation and development process can be comprehensively observed from multiple directions and at multiple angles, a user is convenient to intuitively and clearly observe influence of terrain, cloud mass and air field on cloud, and an effective support is provided for research of a rainfall cloud system structure and research of a rainfall formation mechanism.

Description

technical field [0001] The invention relates to the technical field of three-dimensional display of cloud radar, in particular to a method for three-dimensional display of cloud radar echoes based on full airspace multi-directional scanning mode. Background technique [0002] One of the functions of the millimeter-wave cloud radar data processing terminal is to use a large number of graphics to represent various weather phenomena, including static and dynamic analysis of meteorology, enlarged display of local analysis, and analysis of radial structures. At present, most terminal products represent three-dimensional structures in two-dimensional form. The most representative representation methods are PPI (Plan Position Indicator), RHI (Range Height Indicator), and THI (Time Height Indicator). These methods provide us with Useful information, but they are limited to 2D representations only. [0003] The traditional volume-scanning VCP mode of weather radar has static cone bl...
