Embodiment Construction

[0051] The present invention will be further described below in conjunction with the accompanying drawings,

[0052]like figure 1 As shown, the spatial interpolation method applicable to the microwave link monitoring network of the present invention includes the following steps: for three microwave links in a square area:

[0053] S1, segment each link, and directly specify that the number of virtual sites to be divided by each link is the same value m k =3, all links are equally divided into 3 segments, and the midpoint of each segment is used as the location of the virtual site;

[0054] S2, calculate the error variance of each link due to the antenna accuracy:

[0055]

[0056] Among them, Q k is the lowest value of the antenna accuracy of the kth link; a k , b k is the ITU-R model parameter value corresponding to the microwave at this frequency, and its value is related to the microwave frequency, polarization mode and rainfall particle shape, and can be obtained f...

Abstract

The invention discloses a space interpolation method suitable for a microwave link monitoring network, comprising the following steps: dividing the link into segments, and using the central point of each small segment as the position of a virtual station; calculating the error variance of each link due to the antenna accuracy ; Determine the known points corresponding to each virtual station in all links and their distance weights and distribution weights; use the antenna accuracy error variance and distance weights and distribution weights to calculate the weight matrix of each virtual station; use the matrix weight to perform link-by-link Through iterative calculation, the calculation results of the virtual stations of each link are obtained; the grid is divided; the spatial distribution of rainfall is obtained through the interpolation of the results of all virtual stations. The present invention can use the rainfall information captured by other links through the step-by-step iterative optimization of the sub-links, give full play to the advantages of the high coverage rate of the microwave link network, and solve the problem of converting path integral data to point-scale data.

Description

technical field [0001] The invention relates to a space interpolation method suitable for a microwave link monitoring network, and belongs to the microwave field. Background technique [0002] In recent years, the technology of rainfall monitoring using microwave link network has received extensive attention. However, a problem that currently restricts the development of this technology is how to use the monitoring results of the monitoring network to obtain the spatial distribution of rainfall. Different from other data types, the monitoring results of microwave links are path integral scales, which cannot be applied to existing applications; in addition, due to the general situation of regional aggregation in microwave link networks, the small-area aggregation of such links will It makes the spatial interpolation results very inaccurate, and cannot correctly express the monitoring advantages of the microwave link network. SUMMARY OF THE INVENTION [0003] Purpose of th...
