Description
Technical field
The present invention relates to radome fields, and in particular to a kind of radome of breakage-proof.
Background technology
In the feelings that field of environment protection is growing, environmental monitoring task quickly increases and environmental management requirement is continuously improved
Under condition, promote environmental monitoring socialized service extremely urgent.The equipment such as current some domestic laser radars, windfinding radar are all
It is fixed point monitoring, monitoring is limited in scope, and the cost of equipment is higher, and a city can not possibly put into many fixed point monitorings and set
It is standby.In order to realize entire The Surroundings in Cities monitoring, the research and development that atmospheric environment solid walks boat observation vehicle are significantly, simultaneously
It can also be used to carry out Environmental emergency monitoring, effectively obtain the current intelligence of pollutant.
The Spatial distributions monitoring to pollutant may be implemented in setting windfinding radar etc. on observation vehicle.Existing radar
The anti-wear property of cover is not high, it is also necessary to is further improved to its performance.
Invention content
The purpose of the present invention is to provide a kind of radomes of breakage-proof, can further promote the resisting breakage of radome
Energy.
The present invention is achieved through the following technical solutions：
A kind of radome of breakage-proof, including silica-base composite material is enhanced by quartz glass, three-dimensional silica fiber fabric
The first layer being mixed with boron nitride, third layer made of the second layer, silicon nitride made of glass cloth honeycomb, glass cloth honeycomb
Manufactured 4th layer, second layer structure is identical with the 4th layer of correspondence with thickness, and layer 5 is identical with the structure of first layer, the
One layer is provided with air layer between the second layer, and the 4th layer is provided with air layer between layer 5.
The present invention is by being improved the radome being arranged at the top of windfinding radar, using quartz glass, three-dimensional quartz
Fabric enhances silica-base composite material, boron nitride, on the one hand can enhance the intensity of dustproof rain cover, carrying, shock resistance
Ability, additionally it is possible to effectively improve wave transparent ability.Air layer, the aerial biography of one side electromagnetic wave are set between each layer
Broadcast that speed is big, on the other hand under the buffering of air layer, more electromagnetic waves transmit away from air layer, rather than as previous
Setting can also reflect a part by second material layer and go out.The thickness of air layer needs to be less than the thickness of other each layers.
Quartz glass, three-dimensional silica fiber fabric enhancing silica-base composite material and boron nitride weight ratio be 2.5~
3.5:1.5~2.5：1.5.
The weight ratio of quartz glass, three-dimensional silica fiber fabric enhancing silica-base composite material and boron nitride is 2.5:2.5：
1.5。
