Description
Technical field
The present invention relates to become Cassegrain antenna, and in particular to one kind becomes Cassegrain antenna reflection noodle producing method.
Background technology
Become Cassegrain antenna to be made up of reflection surface system and an irradiator, reflection surface system includes a rotary parabolic
Face (i.e. primary reflection surface) and a hyperboloid of revolution (i.e. subreflector).The hyperboloid of revolution has two focuses:One focus F1(claim
For virtual focus) overlapped with paraboloid of revolution focus F;Another focus F2(being referred to as real focus), irradiator is positioned over focus F2
Place.These reflectings surface are by sheet metal forming.Change Cassegrain antenna is the spherical wave that irradiator is radiated through subreflector
After the secondary reflection of primary reflection surface two, finally it is radiate with plane wave along antenna axis.
Become Cassegrain antenna require primary reflection surface can reflection electromagnetic wave, again can pass through electromagnetic wave, therefore, become jam lattice
Human relations antenna main reflector is not a complete metal covering, but the parabola of metal grizzly bar composition.
In the prior art, the parabola of metal grizzly bar composition has two kinds of preparation methods:One is, by metal grizzly bar one piece one
Gluing is embedded on main reflector mould, i.e., be molded using concave-convex mold mode, and this method needs laying metal grizzly bar and splicing,
Operating difficulties, Fixture Design is complicated;Two are, by metal grizzly bar one piece, one is bonded on plain cloth, because metal grizzly bar is very thin,
Stretch, it is necessary to very careful, and need cloth being divided into three formation of lots during shaping primary reflection surface, otherwise can be at paraboloidal edge
Produce shirt rim.
Both the above method, it is very thin all to there is metal grizzly bar, the problem of complex operation.If from the good gold of rigidity
Belong to silk, be glued aft antenna and be easily deformed, be difficult to control;If from good toughness, ductile wire, easily by wire
Draw and attenuate, stretch tight not straight, it is impossible to ensure the spacing between metal grizzly bar.This all brings very many difficulties to process.
The content of the invention
Become Cassegrain antenna reflection noodle producing method it is an object of the invention to provide one kind, technique is simple, be easy to behaviour
Make.
To achieve the above object, the present invention provides a kind of change Cassegrain antenna reflection noodle producing method, with metal
Silk is parallel, using nonmetal wire as warp, and wire, nonmetal wire are cross-woven into grizzly bar screen cloth using gauze loom;
According to the requirement of Cassegrain antenna reflector design is become, grizzly bar screen cloth is cut, parabola is pressed into.
Above-mentioned change Cassegrain antenna reflects noodle producing method, wherein, using wire as parallel, using nonmetal wire as warp
Arrange after gauze loom, laterally at interval of certain distance and wire and a root piece brightly painted cotton thread of placement, longitudinal direction is every
It is spaced apart that simultaneously root places a brightly painted cotton thread with nonmetal wire.
Above-mentioned change Cassegrain antenna reflects noodle producing method, wherein, it is horizontal and vertical to place one at interval of 500mm
Brightly painted cotton thread.
Above-mentioned change Cassegrain antenna reflects noodle producing method, wherein, brightly painted cotton thread is using red cotton thread.
Above-mentioned change Cassegrain antenna reflects noodle producing method, wherein, wire selects a diameter of 0.2mm wire,
Nonmetal wire selects a diameter of 0.2mm nonmetal wire.
Above-mentioned change Cassegrain antenna reflects noodle producing method, wherein, wire is copper wire, and nonmetal wire is polyamide fibre
Silk.
Above-mentioned change Cassegrain antenna reflects noodle producing method, wherein, designed according to Cassegrain antenna is become to wire
The requirement of spacing, selects the suitable gauze loom of warp and weft spacing.
Above-mentioned change Cassegrain antenna reflects noodle producing method, wherein, wire line space design is 1.6 ± 0.3mm.
Compared with prior art, the present invention has following technique effect:
The change Cassegrain antenna reflection noodle producing method of the present invention weaves grizzly bar reflecting surface, technique letter using loom
It is single, easy to operate;It can be produced in batches using loom, cost is low;The grizzly bar reflecting surface of braiding can be cut randomly, and compacting is thrown
The ductility of wire and nonmetal wire can be utilized during object plane, by the cooperation of frock and mould, reaches that edge does not produce shirt rim,
Improve yield rate;Positioning precision between red cotton thread is set can improving between wire and be nonmetallic so that primary reflection surface and inverse
Speculum compact dimensions precision is high.
