It is divided into several angle block gauges；
S3, according to a certain percentage distribution scheme the adaptable processing thread of institute's subangle number of blocks, institute with plan-position display
Processing thread is stated to complete apart from height display figure on backstage using the distance height display data collected；
S4, a temporald eixis dial and one are set in plan-position display figure for being selected on indication dial disc
The orient control of orientation scale；
S5, according to orient control on temporald eixis dial selected azimuth scale, the real-time display azimuth scale
Corresponding distance height display figure.
Further, it carries out swept-volume collection Weather information using radar in step S1 to be scanned in real time, weather letter
Breath is real-time Weather information.
Further, it is aobvious apart from height in backstage completion using the distance height display data collected that thread is handled in step S3
Diagram, including：It is high that distance is handled using including but not limited to bilinear interpolation, arest neighbors interpolation method and cressman interpolation methods
Display data is spent, distance height display is drawn using the image processing techniques of including but not limited to openCV, openGL and QT and schemes.
Further, each angle block gauge corresponds to a range from height display figure.
Further, the orient control in step S4, which is one, to be dragged around what the radar center in plan-position display figure rotated
Dynamic item.
Further, plan-position shows that figure is shown in the form of polar；Distance height shows figure with the shape of rectangular co-ordinate
Formula shows that ordinate is height, and abscissa is horizontal distance.
The beneficial effects of the invention are as follows：A kind of weather radar data display methods that the present invention uses, by using multi-thread
Journey technical finesse is depicted as largely referring in conjunction with the orientation of plan-position display figure apart from height display figure apart from height display data
Show dial, fully obtain the two-dimensional signal of weather system, the ability that weather system obtains Weather information amount is improved, to have
Effect improves the accuracy of weather forecast.
Description of the drawings
Fig. 1 is the weather radar data display methods flow chart of the present invention.
Specific implementation mode
With specific embodiment, the present invention will be described below in conjunction with the accompanying drawings, and the present invention is that a kind of weather radar data is shown
Method includes the following steps,
S1, using radar carry out swept-volume collect Weather information, the Weather information include plan-position display data and
Apart from height display data；
Wherein, radar progress swept-volume is collected Weather information and is scanned in real time, and Weather information is real-time weather
Information；It is used to show that radar antenna face orientation to be cutd open with the vertical of object when different Elevation Scannings apart from height display figure
Face figure.
S2, it makes plan-position display figure using the plan-position display data of collection and is incited somebody to action according to Azimuth Resolution
It is divided into several angle block gauges；
When radar antenna was shown with certain Elevation Scanning one week in its median-plane location display figure, survey station surrounding objects object
Distribution situation and its echo strength；Plan-position display figure is shown that radar antenna is located at center in the form of polar,
Object mark echo can be shown with concentric circles.
S3, according to a certain percentage distribution scheme the adaptable processing thread of institute's subangle number of blocks, institute with plan-position display
Processing thread is stated to complete apart from height display figure on backstage using the distance height display data collected；
In the present embodiment, the adaptable processing of the angle block gauge distribution in figure is shown for each plan-position according to a certain percentage
Apart from height display data, including but not limited to bilinear interpolation is utilized when handling thread process data accordingly for thread process
One or more algorithms in method, arest neighbors interpolation method and cressman interpolation methods carry out processing calculating；After the completion of data processing
