[0002] Target drones, as a training device used as a shooting training target, have been widely used in various military exercises or weapon shooting tests. However, since most existing shooting targets are generally fixed structures, that is, shooting targets are connected to fixed target poles, such fixed targets can no longer meet the training needs of the troops. Therefore, in order to increase the difficulty of shooting, they have been developed in the direction of mobile, high-speed, and highly maneuverable target drones.

[0003] The research and design of high-speed, highly maneuverable target drones is currently experiencing rapid growth, prompting a surge in research by major military powers into weapon systems (such as missiles and fighter jets) designed to precisely target these high-altitude, high-speed aircraft. Simulators and real-world target environments are two common testing methods for testing the performance of these weapon systems. While simulators have their practical applications, they cannot replace the use of target drones in real-world target environments. Consequently, high-speed, highly maneuverable target drones are becoming increasingly important in military exercises and weapons testing.

[0004] Application No. 2019113950679 provides an unmanned target drone, comprising: a nose hood, which is a circular cross-section lofted body; a mid-fuselage, located at the rear end of the nose hood, which adopts an area ratio design to ensure that the cross-sectional area of ​​the unmanned target drone varies regularly; a tail fuselage, located at the end of the mid-fuselage away from the nose hood, which has a frustum-shaped structure, the cross-sectional area of ​​which gradually decreases as it moves away from the mid-fuselage; large swept winglets, with two large swept winglets disposed on either side of the mid-fuselage and located at the rear end of the nose hood; wings, with two wings disposed on either side of the mid-fuselage and located at the rear end of the large swept winglets; a horizontal tail, with two horizontal tails disposed on either side of the tail of the mid-fuselage; and a vertical tail, which is disposed vertically at the tail of the mid-fuselage. The aerodynamic shape of the unmanned target drone of the present invention can achieve high-speed and high-maneuverability flight, and can meet the research, identification, and evaluation of aviation / air defense weapon systems of various scientific research units, as well as troop training and exercises.

[0005] Its defects are that, first, it is an unmanned target drone and cannot train the operator's driving skills; second, it has a high degree of integration and cannot meet the requirements of long-distance transportation and on-site installation and adjustment.

DETAILED DESCRIPTION

[0027] The present invention will be described in further detail below with reference to the accompanying drawings.

[0028] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0029] A radar antenna, such as Figure 4 and Figure 5 As shown, it includes a shell 31 and a radar 2 installed on the upper part of the shell 31. The shell 31 of this embodiment is a shell with a hollow structure, and a connecting component 3 installed in the shell 31. The connecting component 3 is connected to two oppositely arranged hanging rods 32. The ends of the two hanging rods 32 respectively extend from the shell 31. The connecting component 3 is used to connect the angles of the hanging rods 32 so that the two hanging rods 32 away from the ends of the connecting component 3 are away from each other or close to each other. The ends of the hanging rods 32 away from the connecting component 3 are respectively fixed with hanging parts 321, and the hanging parts 321 are provided with hanging holes 322.

[0030] According to a specific embodiment of the present invention, a connecting assembly 3 is disposed within a housing 31. By operating the connecting assembly 3, the housing 31 and the radar 2 atop it can be detached from the fuselage 1, or the housing 31 and the radar 2 atop it can be fixed to the fuselage 1. The connecting rods 32 extend from the housing 31 at opposite ends, forming an acute angle. This allows the connecting assembly 3 to be positioned substantially parallel to each other, allowing the connecting member 321 to be fixedly connected to the fuselage 1. This facilitates removal and installation of the radar 2 by the operator, thus meeting the requirements of long-distance transportation and on-site adjustment.

[0031] Furthermore, the connecting assembly 3 includes a driving unit 33 and an execution unit 34, the driving unit 33 is used to drive the execution unit 34 to move, the execution unit 34 is located on both sides of the driving unit 33 and slides with the driving unit 33, and the execution unit 34 is respectively connected to a corresponding one of the hanging links 32 and is slidably connected to the end of the hanging link 32 located in the shell 31.

[0032] Furthermore, the driving unit 33 includes a rotating rod 331, a connecting rod 332 and a connecting ring 333. The rotating rod 331 is horizontally arranged in the shell 31. The rotating rod 331 has an external thread. The external thread is located near the end of the rotating rod 331 located in the shell 31. This end of the rotating rod 331 is rotatably connected to the inner wall of the shell 31. A bearing can be installed on the shell 31, and this end of the rotating rod is inserted into the bearing. The connecting ring 333 has an internal thread and is threadedly connected to the rotating rod 331. A connecting rod 332 is fixed on both sides of the connecting ring 333. Specifically, the connecting rod 332 can also adopt an integrated structure, that is, there is only one connecting rod 332, and the middle part of the connecting rod 332 can be fixed to the connecting ring 333, and the two connecting rods 332 are in the same straight line and are arranged perpendicular to the rotating rod 331. One end of the rotating rod 331 extends out of the shell 31. A limited rotation ring 334 is fixedly installed on the inner wall of the shell 31. The limited rotation ring 334 has a hole. The limited rotation ring 334 is sleeved on the end of the rotating rod 331 located in the shell 31. The rotating rod 331 can rotate in the limited rotation ring 334. One end of the rotating rod 331 extending out of the shell 31 is clearance-fitted with the shell 31. A bearing can be installed on this end to reduce the friction between the rotating rod 331 and the shell 31 when the rotating rod 331 rotates.

[0033] Furthermore, the rotating rod 331 is rotatably connected to a rotating head 335 at one end extending out of the housing 31 . The rotating head 335 can facilitate the operator to rotate the rotating rod 331 . The shape of the rotating head 335 is not limited here and can be a disc-shaped structure with a larger diameter.

[0034] Furthermore, the execution unit 34 includes two sliders 341 and two guide rods 343. The two guide rods 343 are symmetrically arranged on both sides of the rotating rod 331 and are connected to the end of the rotating rod 331. One end of the two guide rods 343 can be hinged to the rotating rod 331. The ends of the two guide rods 343 away from the rotating rod 331 are fixed to the shell 31. The ends of the two guide rods 343 can be connected to the inner wall of the shell 31 by fasteners. Both of the guide rods 343 form an acute angle with the rotating rod 331, which is conducive to the movement of the slider 341 in the axial direction of the guide rod 343. The guide rods 343 correspond to the slider 341 one by one. The guide rods 343 pass through the holes opened on the slider 341, and the slider 341 also slides with the connecting rod 332. Similarly, the connecting rod 332 also passes through the hole opened on the slider 341. The guide rod 343 and the connecting rod 332 each pass through different holes and slide with the slider 341 respectively, so that the slider 341 can also move along the guide rod 343 as the connecting rod 332 moves.

[0035] According to a specific embodiment provided by the present invention, this embodiment provides a specific structure of an execution unit 34, and the execution unit 34 can move under the drive of the driving unit 33, so that the execution unit 34 simultaneously drives the respective connected hooking links 32 to rotate.

[0036] Furthermore, the slider 341 is provided with a strip groove 342, which is distributed along the axis direction of the rotating rod 331, that is, opened along the moving direction of the connecting ring 333. The slider 341 is slidingly connected to the hanging link 32 through the strip groove 342, so that when the rotating rod 331 rotates, the slider 341 can move along the guide rod 343 under the restriction of the guide rod 343.

[0037] In this embodiment, a connection method for the hooking link 32 and the housing 31 is provided, and the slider 341 is provided with a strip groove 342 or a strip hole. A connecting head is fixed to the end of the hooking link 32, and the connecting head is inserted into the strip groove 342 or the strip hole. In this way, when the two sliders 341 move along the guide rod 343, the distance between the two sliders 341 increases or decreases, driving the hooking link 32 to rotate.

[0038] According to a specific embodiment provided by the present invention, a hinge ring 323 is fixed to the inner wall of the housing 31, and a hinge shaft 324 is fixed to the hook link 32. The hinge ring 323 is sleeved on the hinge shaft 324 on the outside of the hook link 32. The hinge ring 323 and the hinge shaft 324 are rotatably engaged, and a slider 341 is located above the hinge ring 323. During use, when the screw rod is rotated, the slider 341 drives the hook training rod to rotate about the hinge ring 323 as the axis, similar to the principle of a lever.

[0039] In addition, the present invention also seeks to protect a target drone, such as Figure 1-Figure 3 As shown, it includes a fuselage 1, which is equipped with side wings 11 and a tail 12, the side wings 11 are equipped with engines, a cockpit is provided in the fuselage 1, and any one of the above-mentioned radar 2 antennas is installed on the upper part of the fuselage 1;

[0040] A radar base 13 is mounted on the upper portion of the fuselage 1 and secured to the upper portion of the fuselage 1 via two lower connecting plates 133. Two opposing mounting ears 131 are secured to the radar base 13. These ears 131 extend toward the mounting member 321 to form mounting posts 132, allowing the mounting posts 132 to be inserted into or extended from the mounting hole 322 of the mounting member 321 after the mounting link 32 is rotated. A countersunk hole is provided on the side of the mounting member 321 facing the mounting ears 131 to facilitate insertion of the mounting ears 131.
