An Adaptive Cooperative Scanning Method Based on Networked X-band Radar

Abstract

The invention discloses an adaptive collaborative scanning method based on a networked X-band radar. According to the radar data in the observation area, the networked weather radar recognizes weather features of different scales as trigger conditions, and adaptively starts different scanning strategies. In the present invention, the weather characteristics of different scales identified according to the networked weather radar data are used as trigger conditions, and different scanning strategies are adaptively started, which maximizes the effective detection capability of each radar in the networked radar without affecting the puzzle effect of the networked radar Based on this, it is more capable of detecting the three-dimensional structural characteristics of the storm cell with higher precision.

Description

technical field

[0001] The invention relates to a meteorological detection method, in particular to a strategy formulation method based on networked X-band radar cooperatively scanning multiple weather types. Background technique

[0002] In the field of meteorological detection, at present, a single S(C) band weather radar is mainly used to detect weather systems, which has the disadvantage of insufficient ability to detect the lower atmosphere, and the influence of changes in the atmospheric airflow field that affects the occurrence and development of strong winds and small-to-medium-scale convective weather events The ability to observe the vertical structure is weak, and the ability to observe the evolution of the atmospheric flow field is obviously insufficient. For γ-mesoscale convective cells and smaller-scale tornado weather, the time and spatial resolution of the volume scan mode of existing radars is relatively poor. Processes (such as tornadoes, hail, etc.) have ...

Embodiment

[0025] Embodiment: An adaptive cooperative scanning method based on networked X-band radar. The networked weather radar recognizes weather features of different scales according to the radar data in the observation area as trigger conditions, and adaptively starts different scanning strategies. The cooperative command system of the networked radar commands the scanning mode of each radar in the networked radar according to the scanning strategy.

[0026] In this embodiment, four kinds of scanning strategies are designed according to the different weather systems, namely a, clear sky mode, b, precipitation mode, c, storm mode and d, tornado mode, and the scanning levels of each scanning strategy increase successively, respectively It is grade 1, 2, 3, 4. When the weather system recognizes features that meet multiple trigger conditions, the scanning strategy mode with the highest scanning level is preferentially activated. That is, when multiple weather systems appear in the ob...
