Secondary windfinding radar sum-difference loop assembly

Abstract

The second wind measurement radar sum-diff-ring group is a microwave component for second wind measurement radar angle error extraction, and the component included the network with several different impedance transmission lines, and the transmission line selecting open-slotted transmission line form, and the whole sum-diff-ring component is realized by slotted on both sides of the aluminum board;and the positive side of the aluminum board is two '8' shaped transmission lines, divided into the up-and-down ring composed of 'AB transmission line, DE transmission line, FG transmission line, ADF transmission line, BEG transmission line', and left-and-right ring composed of 'A'B' transmission line, D'E' transmission line, F'G' transmission line, A'D'F' transmission line, B'E'G' transmission line'; in which, each ring is divided into the upper half sum-diff-ring composed of 'AB transmission line, DE transmission line, AD transmission line, BE transmission line' and the lower half modulationring composed of 'FG transmission line, DF transmission line, EG transmission line'.

Description

technical field [0001] The invention relates to a microwave component used for extracting the angle error of a secondary wind-measuring radar, and relates to the technical field of microwave transmission. Background technique [0002] Before the successful development of the new wind measuring radar, the high-altitude meteorological detection network used a large number of 701 secondary wind measuring radars, which were successfully developed in the early 1960s and put into commercial use. There are disadvantages such as backward technical system, low detection accuracy, low degree of automation, serious co-channel interference, large size, heavy weight, etc., especially the angle tracking cannot be automated, which makes the labor intensity of the operator particularly high, because it takes 90 minutes to put the ball The internal operator must keep a firm eye on the change of the target angle, and the accuracy of the data will be affected if there is a slight negligence. ...
