The invention is light and portable, can float on the water surface for use, and is convenient to operate.
Description
Technical Field
The invention relates to a radar reflector, in particular to a flexible foldable floatable radar reflector.
Background
The angle reflector is generally composed of a plurality of metal sheets, the metal sheets are mutually vertically crossed to form a geometric shape which can strongly reflect radar wave signals, when radar electromagnetic waves scan the angle reflector, the radar electromagnetic waves are refracted and amplified on a metal angle to generate extremely strong echo signals, and a very strong echo target appears on a radar screen, so that the angle reflector is widely applied to the fields of military affairs, ship distress, lifesaving and the like. Traditional corner reflector makes different specifications according to different usage through sheet metal, and sheet metal adopts metal aluminium to make more, and the accessory is loaded down with trivial details, needs the field assembly, and the shape is fixed, and the packing is bulky and heavy, can't float, can only fix on the concrete position of equipment, is difficult to accomodate and carry, and the use procedure is complicated moreover.
Disclosure of Invention
The invention aims to provide a flexible, foldable and floatable radar reflector which is light and portable, can be used by floating on water and is convenient to operate.
The technical scheme adopted by the invention is as follows:
the utility model provides a flexible collapsible floatable radar reflector, includes can with aerify mechanism complex gasbag, the gasbag main part adopts the flexible waterproof material that can filter, is equipped with the corner reflector of making up by a plurality of flexible conductive fabric in the gasbag, and each angle of corner reflector is connected respectively on the corresponding position of gasbag inner wall, and the gasbag is aerifyd the corner reflector and is expanded and take shape.
Further, the conductive fabrics are perpendicular to each other to form a plurality of square, triangular or round-edged basic reflection units.
Furthermore, each corner of the corner reflector is sewed with a fixing loop, the inner wall of the air bag is sewed with a fixing loop, and the fixing loops on each corner are connected with the corresponding fixing loops on the inner wall of the air bag through elastic bands.
Furthermore, the bag body is spherical, the two ends of the bag body are provided with round sheets, a plurality of cut sheets are arranged between the round sheets, and the round sheet at one end is matched with the inflation mechanism.
Further, the airbag main body is transparent.
Further, the main material of the air bag is a polyurethane film or a PVC film.
The invention has the beneficial effects that:
the corner reflector is sewn by conductive fabric, when the corner reflector is not used, the air bag is decompressed and is folded and packaged together with the corner reflector inside, and the corner reflector is light and portable; when in use, the air bag is inflated to form, and the corner reflector inside the air bag is unfolded while floating on the water surface, so that the effect of reflecting radar waves can be realized, and the operation is convenient; the corner reflector and the air bag have simple structures and convenient manufacture, and can be processed into different sizes according to different application scenes; the invention can replace most of the traditional corner reflectors and be used in the fields of military affairs, ship distress lifesaving and the like.

Detailed Description
The invention is further illustrated by the following figures and examples.
As shown in fig. 1, a flexible foldable floatable radar reflector comprises an airbag 2 capable of being matched with an inflation mechanism 4, a main body of the airbag 2 is made of flexible waterproof materials capable of filtering, a corner reflector 1 made of a plurality of flexible conductive fabrics through sewing is arranged in the airbag 2, each corner of the corner reflector 1 is connected to a corresponding position on the inner wall of the airbag 2, and the corner reflector 1 is unfolded and formed after the airbag 2 is inflated. The corner reflector 1 is sewn by conductive fabric, when the corner reflector is not used, the air bag 2 is decompressed and is folded and packaged together with the corner reflector 1 inside, and the corner reflector is light and portable; when in use, the air bag 2 is inflated to be formed, and the corner reflector 1 in the air bag is unfolded while floating on the water surface, so that the effect of reflecting radar waves can be realized, and the operation is convenient; the corner reflector 1 and the air bag 2 have simple structures and convenient manufacture, and can be processed into different sizes according to different application scenes; the invention can replace most of the traditional corner reflectors and be used in the fields of military affairs, ship distress lifesaving and the like.
As shown in fig. 1 and 2, the conductive fabrics are perpendicular to each other to form a plurality of square, triangular or circular basic reflection units, typically eight basic reflection units.
As shown in fig. 2 and fig. 3, in the present embodiment, each corner of the corner reflector 1 is sewn with a fixing tab 3, the inner wall of the airbag 2 is sewn with a fixing tab 6, and the fixing tabs 3 at each corner are connected with the corresponding fixing tabs 6 on the inner wall of the airbag 2 through elastic bands. The elasticity of the elastic band has a certain buffering effect, and the conductive fabric is prevented from being excessively stretched and torn when the air inflation is too fast.
As shown in fig. 1, in the present embodiment, the bag body 2 is spherical, two ends of the bag body 2 are circular sheets, a plurality of cut sheets 5 are arranged between the circular sheets, and one end of the circular sheet is matched with the inflation mechanism 4. The circular sheet can prevent all the cut pieces 5 from being sewn at the end part together, and is convenient to assemble with the inflation mechanism 4.
The main body of the air bag 2 is transparent, so that the unfolding condition of the internal corner reflector 1 can be conveniently observed, and the main body material of the air bag 2 can be a polyurethane film, a PVC film and the like.
It will be understood that modifications and variations can be made by persons skilled in the art in light of the above teachings and all such modifications and variations are intended to be included within the scope of the invention as defined in the appended claims.
