Problems solved by technology

[0005] The key flaw in the above method is that it is impossible to answer whether the selected operation unit has changed in the natural state without operation, that is to say, the difference between the parameters after the operation and before the operation is not all the effect of the cloud seeding operation, but Incorporates natural cloud variation

Abstract

The invention discloses a cloud-seeding operation effect radar detection time sequence contrast analysis method and device. The method comprises the steps: selecting a natural cloud unit as a contrast unit of a cloud-seeding operation unit, wherein the natural cloud unit is the most similar to the cloud-seeding operation unit; extracting a third radar detection time subsequence of the cloud-seeding operation unit after an operation moment; comparing the third radar detection time subsequence with a fourth radar detection time subsequence of the contrast unit for analysis; removing the difference between a first radar detection time subsequence and a second third radar detection time subsequence of the cloud-seeding operation unit and the contrast unit before the operation moment, and determining a cloud-seeding operation effect. Compared with the scheme in the prior art, the method removes the inaccuracy, caused by natural changes of the natural cloud unit, of the determination of the cloud-seeding operation effect to the greatest extent, so the method provided by the invention can obtain more accurate cloud-seeding operation effect.
