Embodiment

[0055] An expandable-foldable RCS adjustable reflector of the present invention includes 12 corner reflector units, wherein the lengths of the upper chord 1 and the support rod 2 of each unit are 213.38mm and 308.84mm respectively, and the outer diameters are both 5mm , The outer diameter of the sleeve used for the hinge in the joint structure is 7mm and the inner diameter is 5mm. The support frame of the reflector is composed of the upper chord 1 and the support rod 2 made of carbon fiber hollow rods, and each joint hinge structure. The reflective surface is fixed on each support rod 2 by a wire mesh through a special adhesive.

[0056] Since the upper chord 1 and the support rod 2 are carbon fiber hollow rods, each hinged joint structure is made of aluminum-magnesium alloy, and the wire mesh reflective surface ensures the characteristics of light weight and high structural strength of the overall device of the present invention. The usual corner reflector array has a weight ...

Abstract

The invention discloses an unfoldable-foldable RCS adjustable reflector and a regulation and control method thereof, the reflector comprises a layer of reflector assembly and another layer of reflector assembly arranged in a mirror image manner, each reflector assembly comprises n reflector units connected with each other, and n is a positive integer greater than or equal to 6; the two layers of reflector assemblies are correspondingly hinged through n supporting points of each layer to form a movable structure; and each layer of reflector assembly is provided with an unfolding-folding mechanism, the unfolding-folding mechanisms are used for enabling the whole RCS adjustable reflector capable of being unfolded and folded to be unfolded or folded about an unfolding-folding axis, the unfolding-folding axis is a connecting line passing through the centers of the two splicing aperture faces, and the RCS is adjusted and controlled through different unfolding degrees of the splicing aperture faces. The problems that in the prior art, the product structure size is fixed, and RCS regulation and control cannot be carried out or RCS regulation and control within a very small range exist are solved.

Description

technical field [0001] The invention belongs to the technical field of radar, and in particular relates to a deployable-contractable RCS adjustable reflector and a control method thereof. Background technique [0002] As the current electromagnetic environment becomes more and more complex, the development of electronic countermeasures is getting faster and faster, and the development of reflectors cannot keep up with the pace of demand. Existing reflector products often have a fixed size, volume, and large weight. They have disadvantages such as troublesome and bulky in use and transportation, and cannot meet the requirements of easy transportation, loading and light weight, and when the size and volume are fixed, they often Without the ability of RCS regulation, it cannot meet the requirements for different scattering characteristics and the requirements for convenient use, transportation and loading in today's complex electromagnetic environment. [0003] Some existing r...
