Embodiment

[0048] The ultimate goal of the 3D cloud field generation technology is to be able to provide the cloud droplet density at any position in a certain airspace. Considering the characteristics of the fast maneuvering speed of the aircraft, the airspace generally has a large range. On the other hand, the airborne weather radar simulation application simulates access to this airspace only at sparse positions on the radar wave scanning line, such as figure 2 For the cone-shaped area shown, it is only necessary to provide an API interface to return the cloud droplet density at any position, and it is not necessary to calculate the dynamic changes of cloud droplet density at all positions in the entire cloud field.

[0049] Such as figure 1 As shown in the three-dimensional schematic diagram of the grid, in order to generate large-scale cloud field data, the present invention uses satellite cloud image information as the initial seed, grows a three-dimensional cloud field in the for...

Abstract

The invention relates to a three-dimensional cloud field generating method based on airborne weather radar simulation. The method is used for external environment simulation of an airborne weather radar. The method comprises the steps that 1) dynamic satellite cloud image data are acquired and are used as the information source of a simulation three-dimensional cloud field; 2) according to the dynamic satellite cloud image data, a cellular automata iteration method is used to generate cloud droplet density in a simulation three-dimensional cloud field; 3) a dual two-dimensional grid local iteration method is used to carry out data updating on a space related to test in the generated simulation three-dimensional cloud field; and 4) according to the three-dimensional cloud field after data updating and a state query interface, a simulation test is carried out on the external environment of the airborne weather radar. Compared with the prior art, the method provided by the invention has the advantages of less memory, less calculation data, high accuracy, flexible application and the like.

Description

technical field [0001] The invention relates to the field of meteorological detection and computer simulation, in particular to a three-dimensional cloud field generation method based on airborne weather radar simulation. Background technique [0002] Airborne Weather Radar (Airborne Weather Radar) can detect the weather conditions in the flight path ahead of the aircraft, including thunderstorms, hail, storms, turbulence, clouds and microstorms, etc., to help pilots correctly assess the weather situation, which is important for flight safety and flight quality The support function has become an indispensable and important part of large civil aircraft. The development process of traditional airborne weather radar can only carry out power-on inspection and static test of the physical prototype on the ground, and the comprehensive performance test must be completed through test flight. However, in the flight test, the actual flight environment selection, flight test, and dyna...
