Embodiment 1

[0032] like figure 1 , figure 2 , image 3 , Figure 4As shown, a programmable reflector in this embodiment includes a reflector array 11 and a coding master control device 12; the reflector array 11 includes 30 reflection units 13, and the 30 reflection units 13 are formed by a planar rectangular array In the reflector array 11, the distance D between two adjacent reflecting units 13 is 30 cm. Each reflecting unit 13 includes a base 14 , an electromagnetic wave lens 15 , a rotating mechanism 16 and a reflecting member 17 . The rotating mechanism 16 is mounted on the base 14 . The electromagnetic wave lens 15 is a spherical structure. The rotation axis of the electromagnetic wave lens 15 relative to the base 14 is L1 . The electromagnetic wave lens 15 is driven by the rotating mechanism 16 to move relative to the base 14 . The structure that the electromagnetic wave lens 15 is installed on the base 14 is specifically: a rotating part 151 is fixed on both sides of the ele...

Embodiment 2

[0036] The difference between this embodiment and Embodiment 1 is that: the reflection combination figure is formed by the combination of the reflection units 26 of 4 kinds of target postures; Figure 5 As shown, there are five rows of reflection units 26 in this embodiment, from top to bottom are the first row 21 , the second row 22 , the third row 23 , the fourth row 24 and the fifth row 25 , wherein the first row 21 , the third row 25 The reflection unit 26 in the five elements 25 is in the first target attitude, and the central reflection direction of the main reflection surface of the reflector 27 of the reflection unit 26 in the first target attitude is the inward direction perpendicular to the paper surface; the second The reflection unit 26 in row 22 is in the second target attitude, the reflection unit 26 in the fourth row 24 is in the third target attitude, and the reflector of the reflection unit 26 in the second row 22 The central reflection direction of the main r...

Embodiment 3

[0038] The difference between this embodiment and Embodiment 1 is that: Image 6 As shown, the outline shape of the reflector array 32 in this embodiment is a triangle, and the reflecting units 31 in the first reflecting state of the reflector array 32 under the action of the encoding master device 33 together form a "herringbone"-shaped pattern . like Image 6 As shown, in the reflection unit 31 in the first reflection state, no reflection member can be seen, and the central reflection direction of the main reflection surface of the reflection member of these reflection units 31 is perpendicular to the outward direction of the paper surface. Such a design can reflect different radar wave reflection characteristics from Embodiment 1 when in use, so as to meet the needs of different application scenarios.

Abstract

The invention relates to a programmable reflector. The programmable reflector is characterized by comprising a reflector array and a coding master control device, the reflector array comprises at least two reflecting units; each reflecting unit comprises a base, an electromagnetic wave lens, a rotating mechanism and a reflecting piece; the rotating mechanism is mounted on the base; the electromagnetic wave lens is driven by the rotating mechanism to move relative to the base, a reflecting part moving along with the electromagnetic wave lens is further arranged on the electromagnetic wave lens, one surface, facing the electromagnetic wave lens, of the reflecting part is a main reflecting surface, and the other surface is a secondary reflecting surface; the coding master control device is electrically connected with the rotating mechanism of each reflection unit so as to control the rotating mechanism of each reflection unit, and then the action time and the target posture of each electromagnetic wave lens and each reflection piece are controlled. The structure is simple, the design is reasonable, different electromagnetic wave reflection combination patterns can be formed, and different radar wave reflection characteristics can be formed.

Description

technical field [0001] The invention relates to the technical field of communication equipment and radar, in particular to a programmable reflector. Background technique [0002] At present, in order to find the location of the target, the technical means of optical imaging and radar imaging are usually used to achieve it. Optical imaging (including infrared imaging) is usually used to find targets on airborne and satellites. influences. Radar imaging is a technical means of finding targets all-weather, and can detect the features of the equipment below through camouflage, but the imaging clarity is not as good as optical imaging. With the development of computer technology, traditional electronic countermeasures have been unable to complete the camouflage and concealment of the target. In order to effectively protect the target, it is necessary to design a multi-functional technical covert jamming device for the means of finding the target, change the characteristics of ...
