[0041] Reference Figures 1 to 9 The present application provides a spherical target, comprising: an inflatable sphere 1, a flexible corner reflector 4, a self-destruction device 6 and a control box 3; the inflatable sphere 1 is provided with the flexible corner reflector 4, the flexible corner reflector 4 is a polyhedral structure, the self-destruction device 6 is arranged on the inner wall of the inflatable sphere 1, and the control box 3 is arranged in the inflatable sphere 1; the control box 3 is electrically connected with the self-destruction device 6, and is used for controlling the self-destruction device 6 to destroy the inflatable sphere 1; the control box 3 is provided with a communication module, and the communication module is used for receiving and transmitting information.

[0042] As a person skilled in the art should understand that the inflatable sphere 1 adopts a wave-penetrable flexible cloth and is formed by high-frequency blow welding. The inflatable sphere 1 is provided with an inflation valve 11 and an air-tight zipper 12. The inflatable sphere 1 can be inflated and pressure tested through the inflation valve 11. The air-tight zipper 12 is used for installing and adjusting the equipment and devices in the inflatable sphere 1. A plurality of flexible hanging rings 13 are welded on the inner wall of the inflatable sphere 1 by high-frequency welding, and the flexible corner reflector 4 is connected by elastic ropes 41. It can be understood that the flexible hanging ring 13 and the inflatable sphere 1 adopt the same material cloth.

[0043] In this embodiment, referring to Figure 1 and Figure 5 , the flexible corner reflector 4 is sewn by silver ion flexible cloth. Since the flexible corner reflector 4 adopts silver ion flexible cloth, a plurality of elastic ropes 41 are needed to pull and form it to ensure that it has a full circumferential reflection characteristic, thereby forming a radar wave passive jamming. Preferably, the unfolded state of the flexible corner reflector 4 is a regular octahedron structure, which is sewn by two square and four triangular silver ion flexible cloths.

[0044] In this embodiment, due to the material characteristics of the inflatable sphere 1 itself, the material characteristics of the flexible corner reflector 4, and the connection mode of the elastic ropes 41, the inflatable sphere 1 itself does not affect the use function after being unfolded when it is not inflated and folded. At the same time, the elastic rope 41 connection has an elastic connection mode, which ensures that the inflatable sphere 1 will not affect its reflection characteristic when it is impacted by sea waves on the sea surface or by wind pressure on land, and will not cause radar wave failure.

[0045] In one of the embodiments, referring to Figure 1 , Figure 7 and Figure 8 , the application also includes a smoke device 5, which includes a column structure and a circular ring extending outwardly in the circumferential direction of the middle part of the column structure. A plurality of convex concentric circular platforms are arranged on the axial surface of the circular ring, and the cross section of each convex concentric circular platform is triangular. An outer thread is arranged on the outer wall of the column structure in the circumferential direction, which is connected with a threaded flange. A plurality of concentric circular grooves are arranged on one axial surface of the threaded flange, and the cross section of each concentric circular groove is triangular, which can be transitionally matched with each convex concentric circular platform. When installed, one end of the smoke device 5 penetrates out of the inflatable sphere 1 and is threadedly connected with the threaded flange 54. By screwing the threaded flange 54, the threaded flange 54 is attached to the circular ring and clamps the inflatable sphere 1. The structure of the concentric circular ring and the concentric circular groove realizes the sealing of the connection.

[0046] The smoke generator 5 is electrically connected with the control box 3 through a smoke generator cable 53. It should be understood that the smoke generator 5 is sealingly connected with a threaded flange, which is sealingly connected on the inflatable sphere 1. The smoke generator 5 can be loaded with smoke agents 51 of multiple colors. The operator controls the smoke generator 5 through the control box 3, so that the smoke agents 51 in the smoke generator 5 generate a large amount of smoke under the action of an electric current, which is discharged through a smoke outlet 52. The large amount of smoke forms a smoke ring around the inflatable sphere 1, thereby forming smoke interference to the radar.

[0047] With reference to Figure 1 and Figure 4 , the control box 3 comprises a battery 33 and a circuit board 31 connected with the battery 33. The circuit board 31 is provided with a Beidou positioning module and a communication module. The Beidou positioning module is used for positioning, and the communication module is used for receiving and sending instructions of the operator. The control box 3 is provided with a plurality of plug-in interfaces, which can be connected with other devices. The battery 33 in the control box 3 supplies power to the circuit board 31, so that the positioning, communication and control functions of the control box 3 work. The control box 3 further comprises an external shell 32, which has sealing property and protects the internal circuit board 31.

[0048] In one embodiment, with reference to Figure 1 and Figure 3 , the inflatable sphere 1 is provided with an infrared device 2 on the inner wall, which is connected with the battery 33 and the circuit board 31. The infrared device 2 comprises a plurality of flexible infrared foil strips, each of which is arranged on the inner wall of the inflatable sphere 1 at a position corresponding to each edge of the flexible corner reflector 4. The infrared device 2 can form a local thermal imaging space in the interior of the inflatable sphere 1. The battery 33 supplies power to the infrared device 2. The infrared foil strips are made of flexible material, so that the inflatable sphere 1 can be folded. As a person skilled in the art can understand, the infrared foil strips are heated by the battery 33. Therefore, they are arranged on the inner wall of the inflatable sphere 1 at positions corresponding to each edge of the flexible corner reflector 4, so as to reduce the influence on the radar cross section. In addition, the infrared device cable 21 is connected in parallel with each flexible infrared foil strip, so as to ensure thermal imaging interference.

[0049] With reference to Figure 1 and Figure 6The self-destruction device 6, the control box 3 and the smoke emitting device 5 are arranged on the inflatable sphere 1 at positions corresponding to each vertex of the flexible corner reflector 4. It should be understood that each vertex of the flexible corner reflector 4 is removed partially, and the installation positions of the self-destruction device 6, the control box 3 and the smoke emitting device 5 and other devices are reserved, and each device is installed at the vertex to reduce the influence on the radar cross section. In addition, each vertex of the flexible corner reflector 4 is connected to the flexible hanging ring 13 through a plurality of elastic ropes 41 and a plurality of plastic hooks 42, so as to avoid the problem that the small position of each vertex is inconvenient to operate. In an optional embodiment, each vertex of the flexible corner reflector 4 can be connected to the inflatable sphere 1 through the elastic rope 41, the plastic hook 42 and the flexible hanging ring 13.

[0050] Reference Figure 1 and Figure 9 The self-destruction device 6 comprises a crimping disc 61 which is bonded to the inner wall of the inflatable sphere 1, and a cavity is formed between the middle part of the crimping disc 61 and the inner wall of the inflatable sphere 1, and the cavity in the middle part of the crimping disc 61 is a semicircular structure; a spring 62 is arranged in the cavity; a high-temperature ceramic heating sheet 63 is arranged in the cavity and is pressed against the inner wall of the inflatable sphere 1 through the spring 62, and the high-temperature ceramic heating sheet 63 is electrically connected to the control box 3. In an optional embodiment, the first end of the spring 62 is connected to the crimping disc 61, the second end of the spring 62 is connected to the high-temperature ceramic heating sheet 63, the high-temperature ceramic heating sheet 63 is heated by electric current, and the temperature can quickly reach above 500, under the action of high temperature, the inflatable sphere 1 can be holed, the gas in the inflatable sphere 1 is discharged and water is filled, and the spherical target is self-destructed.

[0051] The spherical target provided by the application has a full-circumferential field of view through the polyhedral structure composed of the flexible corner reflector 4, and can efficiently realize the radar wave interference characteristics in each direction. The spherical target of the application is also provided with the self-destruction device 6, can be self-destructed, and has interference modes such as thermal imaging interference and smoke interference, and meets the needs of various use scenarios.
