[0042] There are two middle vertical plates 12, which are respectively connected with the two middle vertical plate slots 111 on the bottom support long plate 11, and the middle vertical plates 12 are arranged in the middle area of the tank vehicle target, one of which is located at the head side of the tank vehicle target, and the other is located at the tail side; the middle horizontal support plate 14 is connected with the middle horizontal support plate slot 112 on the bottom support long plate 11, and the middle horizontal support plate 14 is arranged between the two middle vertical plates 12; there are two vertical plate side baffles 13, which are respectively fixed to the two middle vertical plates by Velcro The two vertical plate side baffles 13 are respectively arranged on both sides of the middle horizontal supporting plate 14, that is, the two ends of the vertical plate side baffles 13 are respectively connected to the ends of the two middle vertical plates 12, and are located on both sides of the tank vehicle target; the front oblique support plate 16 is clamped with the front oblique support plate slot 113 on the bottom supporting long plate 11, and the front oblique support plate 16 is located at the head of the tank vehicle target; there are three front side baffles 18, and the three front side baffles 18 are fixed between the front oblique support plate 16 and the middle vertical plate 12 on the head side by Velcro, and the three front side baffles 18 are arranged at the same intervals.

[0044] The middle body 1 further includes a first fixing plate 19 . There are four first fixing plates 19 in total. The four first fixing plates 19 are symmetrically mounted on the side walls at the ends of the two middle vertical plates 12 , that is, the four first fixing plates 19 are symmetrically distributed on both sides of the middle body 1 .
[0045] like Figure 4 As shown, the track assembly 2 includes a tank track side plate 21 , a track skin 22 and a second fixed plate 23 .
[0046] like Figure 1 to Figure 2 As shown, there are two tank track side plates 21, which are respectively installed on both sides of the middle vehicle body 1, and their shapes are consistent with the overall shape of the wheels and tracks when the real tank vehicle is viewed from the side; the second fixed plate 23 is installed on the side of the tank track side plate 21 close to the middle vehicle body 1, and there are four second fixed plates 23, and the installation positions of the four second fixed plates 23 correspond one by one to the positions of the four first fixed plates 19.
[0047] There are two track skins 22, which are respectively mounted on two tank track side plates 21. The outer surface of the track skin 22 is painted with a pattern for simulating the track of a real tank, so that the tank target is similar to the real tank in visual perception. The track skin 22 is a double-layer structure, and different parts of the track skin 22 are respectively provided with absorbing materials and metal materials to improve the accuracy of the collision test results. Among them, the absorbing material can be an absorbing sponge, which can reduce the radar reflection cross section (RCS) of the tank target during the test, and the metal material can be aluminum foil, which can enhance the tank during the test.

[0048] like Figures 7 and 8 As shown, the magnetic attraction mechanism 51 includes a first magnet 511 and a second magnet 512, which attract each other. The number of the first magnet 511 and the second magnet 512 are equal and the positions are corresponding. The first magnet 511 is installed on the first fixed plate 19, and the second magnet 512 is installed on the second fixed plate 23. The tank track side plate 21 is fixed to the middle vehicle body 1 by the magnetic attraction of the first magnet 511 and the second magnet 512.
[0049] The elastic locking mechanism 52 includes a limiting groove 521 and a limiting block 522. The limiting grooves 521 and the limiting blocks 522 are equal in number and corresponding in position. The limiting grooves 521 are installed on the first fixing plate 19, and the limiting blocks 522 are installed on the second fixing plate 23. The limiting blocks 522 match the limiting grooves 521 in shape and can be snapped together. When the tank track side plate 21 is connected to the intermediate vehicle body 1, the limiting and locking are achieved by snapping the limiting grooves 521 and the limiting blocks 522. In this embodiment, the limiting grooves 521 and the limiting blocks 522 are made of elastic material. After snapping, they can cooperate with the magnetic suction mechanism 51 to fix the tank track side plate 21 on the intermediate vehicle body 1 more stably, so that the tank track side plates 21 on both sides of the intermediate vehicle body 1 are aligned, and are not easily misplaced or fall off.
[0050] The launching barrel assembly 3 includes an upper mounting plate 31 , a launcher 32 , a launching barrel mounting plate 33 and a launching barrel 34 .
[0051] The upper mounting plate 31 is fixed above the middle vehicle body top plate 15 by Velcro, and the launching barrel mounting plate 33 is fixed at the middle position above the upper mounting plate 31 by Velcro. There are two launchers 32, which are respectively fixed on both sides of the launching barrel mounting plate 33 by Velcro, and the launching barrel 34 is fixed on the launching barrel mounting plate 33.
[0052] The tail antenna assembly 4 includes a tail transverse plate 41 , a tail boss cover plate 42 , a tail side plate 43 , a tail side cover plate 44 , a tail support plate 45 and an antenna rod 46 .
[0053] The tail cross plate 41 is snapped into the tail cross plate slot 114 on the bottom supporting long plate 11; the two ends of the tail side plate 43 are respectively connected to the tail cross plate 41 and the end of the middle vertical plate 12 on one side of the tail by Velcro, and there are two tail side plates 43, which are respectively located on both sides of the tail cross plate 41; the tail side cover plate 44 is fixed to the upper side of the two tail side plates 43 close to the middle vertical plate 12 by Velcro; the tail support plate 45 is fixed between the tail cross plate 41 and the middle vertical plate 12 on one side of the tail by Velcro, and the distance between the tail support plate 45 and the two tail side plates 43 is equal; the tail boss cover plate 42 is fixed to the upper part of the tail cross plate 41, the tail side plate 43, the tail side cover plate 44 and the tail support plate 45 by Velcro; the antenna rod 46 is fixed on the tail boss cover plate 42.
[0054] In this embodiment, under the support of the two bottom supporting long plates 11, the tank vehicle target object is more stable after assembly, and the middle vertical plate 12, the middle horizontal support plate 14, the front inclined support plate 16 and the tail horizontal plate 41 serving as the supporting skeleton above can be fixed in the corresponding slots on the bottom supporting long plates 11, so that the various components on the head side and the tail side will not fall due to gravity during use.
[0055] In this embodiment, each module of the tank target is connected by magnetic attraction or Velcro bonding, so as to realize the modularization of the whole model, facilitate rapid assembly and disassembly, and can be more widely used in unmanned vehicle test scenarios. The modular tank target in this solution is provided with some parts made of polyethylene foam cotton, which can not only withstand a speed impact of at least 60km / h, but also can be reassembled and reused after completing the impact test. The assembly method of magnetic attraction or Velcro bonding can buffer the impact force, making the tank target easier to recover after being assembled, reducing the situation of the target being crashed, and realizing the reuse of the target. Moreover, during the test, the RCS value of the tank target can be adjusted by adjusting the material inside the track skin 22, so that its RCS value is close to the RCS of the real tank, thereby more realistically restoring the real scene and improving the accuracy of the test results.
[0056] In this embodiment, except for the first fixing plate 19, the second fixing plate 23, the track skin 22 and the connecting assembly 5, all other parts of the tank target are made of high-density polyethylene foam, and these parts are wrapped with a layer of military green skin. Velcro is installed at the position of each part for connecting with other parts. Polyethylene foam, as a new type of environmentally friendly packaging material, has the characteristics of good plasticity and strong toughness, thereby further ensuring that the tank target can withstand the impact of a vehicle speed of 60 km / h.
[0057] When the tank target of this embodiment is used for collision test, a driving bottom plate or a static bottom plate can be set under the tank target to assist in completing the test. When the test scenario requires the tank target to move along a pre-programmed route at a limited speed, the tank target is installed on the driving bottom plate, and the driving bottom plate drives the tank target to move, so that the tank target simulates the driving of a real tank, thereby increasing the comprehensiveness of the simulation scenario; when the test scenario does not require the tank target to move, the bottom plate uses a static bottom plate, and the static bottom plate is made of foam material to save costs. Since the track assembly 2 is fixed to both sides of the intermediate vehicle body 1 by a magnetic attraction mechanism 51, the first magnet 511 and the second magnet 512 therein are prone to relative movement under a large external force, so it is necessary to use Velcro to fix the bottom support long plate 11 and the track skin 22 outside the tank track side plate 21 to the bottom plate, so that the tank target can maintain a relatively stable state and is not prone to dislocation and deformation.
[0058] Before the collision test, the tank target is assembled. The specific process is as follows:
[0059] First, fix the bottom support long board 11 to the pre-prepared driving bottom board or static bottom board through Velcro, and respectively connect the middle vertical board 12, the middle horizontal support board 14, the front oblique support board 16 and the rear horizontal board 41 to the middle vertical board slot 111, the middle horizontal support board slot 112, the front oblique support board slot 113 and the rear horizontal board slot 114 on the bottom support long board 11;
[0060] Then, fix the vertical plate side baffle 13 to the two sides of the middle horizontal support plate 14 by Velcro, fix the front side baffle 18 between the middle vertical plate 12 on the head side and the front oblique support plate 16 by Velcro, fix the front oblique cover plate 17 on the top of the front side baffle 18 by Velcro, fix the middle vehicle body top plate 15 on the top of the middle vehicle body 1 by Velcro, fix the tail support plate 45 between the middle vertical plate 12 on the tail side and the tail horizontal plate 41 by Velcro, fix the tail side plate 43, the tail side cover plate 44 and the tail boss cover plate 42 to the corresponding positions of the tail of the tank target object in turn by Velcro, and install the upper plate 31, the launcher 32 and the launch barrel mounting plate 33 in the corresponding positions above the middle vehicle body 1 in turn by Velcro.
[0061] Finally, the tank track side plate 21 is fixed to the middle vehicle body 1 through the magnetic attraction mechanism 51 and the elastic locking mechanism 52, so that the first magnet 511 is correspondingly combined with the second magnet 512, the limit block 522 is correspondingly engaged with the limit groove 521, and the track skin 22 is sleeved on the outside of the tank track side plate 21, and the track skin 22 is connected to the driving bottom plate or the static bottom plate below through Velcro.
[0062] After the assembly is completed, the next step is to calibrate the RCS of the tank target and make the RCS value basically consistent with the real tank by adding absorbing sponge or aluminum foil. Fig. 9 As shown, the distance (unit m) is used as the horizontal coordinate, and the RCS value (unit dBsm) is used as the vertical coordinate. The RCS value of the real tank is compared with the RCS value of the tank target twice. After calibration, within the range of 0-60m, the RCS curve of the tank target is basically consistent with the rising trend of the RCS curve of the real tank. During use, the host computer is used for data communication. When the active safety recognition failure is displayed, it means that the tank target has collided. During the collision, the fixing method of the magnetic suction mechanism 51 and the Velcro can buffer the impact force. After the test is completed, the tank target can be reassembled for the next test.

For example, "connect" can be a fixed connection, a detachable connection, or an integral connection; "connect" can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
