Description

A kind of method of radar adaptability detection spout

Technical field

The present invention relates to a kind of meteorological sounding technique, more particularly to a kind of method of radar detection spout.

Background technology

The mode of traditional radar detection spout：One kind is that one or several weather thunders are fixedly mounted in the multiple area of spout Reach, wait spout to occur or move into be detected；Another kind is one or several mobile weather radar in spout generation or possible Spout generating region is reached during generation to be detected., equivalent to trusting to chance and strokes of luck, capture rate is low for the former.The latter has mobility, Capture rate is high.But each radar each detects, it is impossible to obtains effective three-dimensional flow field information.

The content of the invention

It is an object of the invention to provide a kind of method of radar adaptability detection spout, to be covered when solving and spout being observed Scope is big, it is fast to reach the observation station time and completely obtains the technical problems such as the three-dimensional flow field of spout.

In order to realize foregoing invention purpose, the technical solution adopted in the present invention is as follows：

N number of point is selected in spout Yi Fa areas, the distance of consecutive points is 60-100 kilometers, and adjacent every three points form a triangle Shape, N number of mobile weather radar is laid in these points respectively, spout without occur time in, every three adjacent radars One group, while the delta-shaped region is scanned, order synergistic observation, obtains three-dimensional detection data successively；When there is spout generation, adjust Whole mobile weather radar position, the moving direction for making above-mentioned N number of mobile weather radar to occur along spout, with adjacent meteorological thunder Distance is arranged in the laying mode that adjacent every three points form a triangle in 20 to 40 kilometer ranges between reaching, dragon Involve in into that triangle, that three radars start simultaneously at triangle corresponding to scanning.

Advantages of the present invention and good effect：

（1）Quiet dynamic combination.Coverage is big during fixed observer, distance 60-100 kilometers between radar；During mobile observation, radar away from From 30 kms, azimuth resolution significantly improves.

（2）Usually movable radar distributed arrangement so that mobile route is short when spout occurs, and the arrival sensing point time is fast, Spout can effectively be captured.

（3）Three radars detect spout simultaneously, can completely obtain the three-dimensional flow field of spout.

Brief description of the drawings

Fig. 1 is the distribution schematic diagram in no generation spout of the present invention.

One of position and direction schematic diagram occur for the spout that Fig. 2 is the present invention.

Fig. 3 is one of layout diagram after movement when spout occurs as shown in Figure 2 of the present invention.

Fig. 4 is that the spout of the present invention occurs the two of position and direction intention.

Fig. 5 be the present invention spout occur it is as shown in Figure 4 when movement after layout diagram two.

Embodiment

The specific detection method of the present invention is as follows：

N number of point is selected in spout Yi Fa areas first, the distance of consecutive points is 60-100 kilometers, and every three points form a triangle （Preferably equilateral triangle）N number of mobile weather radar is laid in these points respectively, spout without occur time in, often Three one group adjacent of radars, synergistic observation, obtain three-dimensional detection data.It is shown in Figure 1, layout when being exactly N=6 Figure.

The combination of synergistic observation and scanning sequency are：（1）1st, 3,4 radars scan 1,3,4 triangles formed simultaneously；（2） 1st, 2,4 radars scan 1,2,4 triangles formed simultaneously；（3）3rd, 5,4 radars scan 3,5,4 triangles formed simultaneously；（4） 4th, 5,6 radars scan 4,5,6 triangles formed simultaneously.Then it is returned to（1）, constantly repeat.

When there is spout generation, if as shown in Fig. 2 spout is likely to occur in position shown in arrow, moving direction is also such as Shown in arrow, then, movable radar is moved rapidly by highway, and it is public to form the distance between Fig. 3 layout, adjacent radar about 30 In, every three adjacent radars are triangle.

When spout enters in the triangle of certain three adjacent radar compositions, these three radars, which start simultaneously at, scans this triangle Shape, during such as spout between the triangle that radar 1,2,3 forms, radar 1,2,3 scans simultaneously, obtains three-dimensional detection data；Dragon Involve in into radar 2,3,4 composition triangle when, radar 2,3,4 scans simultaneously, acquisition three-dimensional detection data.

If spout occurs in position as shown in Figure 4, then, movable radar is moved rapidly by highway, forms such as Fig. 5 About 30 kilometers of the distance between shown layout, adjacent radar, every three adjacent radars are triangle.Radar 1,3,4；1、4、 2；2、4、6；4th, 5,64 triangles are separately constituted.Spout enters that triangle, and it is corresponding that three radars start simultaneously at scanning Triangle.

In Fig. 1-5, A represents land, and B represents ocean.

Claims (2)

1. a kind of method of radar adaptability detection spout, step are as follows：
