Technical Field

[0001] This utility model relates to the field of radar scattering test technology, specifically to a radar scattering test turntable device. Background Technology

[0002] Based on the most basic RCS testing method, extended testing can be carried out by using a moving trolley to perform a circling test on a larger target, thus realizing the RCS testing method for larger targets, such as radar vehicles, aircraft, etc. The conventional testing method is to rotate the target under test inside a microwave anechoic chamber to test RCS.

[0003] However, traditional testing devices cannot meet the detection requirements for large objects and in outdoor environments. Utility Model Content

[0004] The purpose of this invention is to provide a radar scattering test turntable device. The ring rail adopts a ring assembly structure, and the precise connection and locking of multiple rail segments are achieved through locking grooves. This design breaks through the size limitations of traditional integral ring rails and can flexibly expand the rail diameter according to the actual size of the large target being tested, thus solving the problems in the prior art.

In addition, the ring rail is configured as a ring assembly structure, the ring rail includes a track ring groove and four sets of infrared ranging modules, and locking grooves are provided between the ring rails. The infrared ranging modules are located on the inner side of the ring rail. The mounting shaft platform is located above one end of the rocker arm, and the interior of the mounting shaft platform is provided with mounting brackets.

[0006] Through the above scheme, the infrared ranging module continuously monitors the shape of the ring track, providing the system with key attitude data. This data is not only used for leveling control, but can also be used for data post-processing when necessary to correct measurement errors caused by minute deformations.

[0007] Preferably, the two sets of rocker arms are connected by a telescopic bridge, and the outer surface of the rocker arms is provided with a limit groove, and the telescopic bridge is installed inside the limit groove.

[0008] The above solution, with its design of limit grooves, adjustment lock holes, and bolts, provides a robust, reliable, and easy-to-operate mechanism for adjusting the rocker arm spacing.

[0009] Preferably, the outer surface of the telescopic cable tray is provided with an adjustment lock hole, and an adjustment bolt is provided inside the adjustment lock hole. Both ends of the telescopic cable tray are connected to the rocker arm through the adjustment bolt.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This utility model, with its ring-shaped assembly structure, fundamentally solves the problems of manufacturing, transporting, and installing ultra-large diameter tracks, enabling the device to easily cover massive objects that traditional turntables cannot accommodate, such as aircraft fuselages, vehicles, and large antennas. The telescopic bridge, combined with the design of the limiting groove, adjusting lock hole, and locking bolt, provides a robust, reliable, and easy-to-operate rocker arm spacing adjustment mechanism. Without replacing core components, it can quickly adapt to targets of different widths and volumes, greatly improving the equipment's versatility and testing efficiency.

[0016] 2. In this utility model, the independently controlled electric cylinder combined with the real-time feedback of the infrared ranging module constitutes an intelligent leveling system. Even in uneven or sloping outdoor sites, it can dynamically maintain the stability and levelness of the entire test turntable, which is a prerequisite for ensuring high-precision radar scattering measurement.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] To address the issue that traditional testing devices cannot meet the detection requirements for large objects and in outdoor environments; please refer to... Figure 1-3 The present invention provides the following solution:

[0023] refer to Figure 1-2 A radar scattering test turntable device includes a ring rail 1, a rocker arm 2, and a mounting platform 3. The ring rail 1 is configured as a ring assembly structure, including a track ring groove 101 and four sets of infrared ranging modules 102. Locking grooves 103 are provided between the ring rails 1. The infrared ranging modules 102 are located on the inner side of the ring rail 1. The mounting platform 3 is located above one end of the rocker arm 2, and the interior of the mounting platform 3 is provided with mounting brackets 301.

[0024] In this embodiment, the ring track 1 adopts a ring-shaped assembly structure, and the locking groove 103 realizes the precise connection and locking of multiple track segments. This design breaks through the size limitation of traditional integral ring tracks, and the track diameter can be flexibly expanded according to the actual size of the large target being measured. The four sets of infrared ranging modules 102 integrated inside the ring track 1 continuously monitor the distance from different positions of the ring track to the fixed reference point or the ground. These data are fed back to the control system to calculate the flatness and levelness of the ring track in real time, which is the core basis for the electric cylinder 204 to perform precise leveling control.

[0025] refer to Figure 3 The two sets of rocker arms 2 are connected by a telescopic bridge 202. The outer surface of the rocker arm 2 is provided with a limit groove 201. The telescopic bridge 202 is installed inside the limit groove 201. The outer surface of the telescopic bridge 202 is provided with an adjustment lock hole 2021. The inside of the adjustment lock hole 2021 is provided with an adjustment bolt 2022. Both ends of the telescopic bridge 202 are connected to the rocker arm 2 through the adjustment bolt 2022.

[0026] In this embodiment, the two sets of rocker arms 2 are connected by a telescopic bridge 202. The telescopic bridge 202 is embedded in the limiting groove 201 on the outer surface of the rocker arm, and is mechanically locked by inserting the adjusting bolt 2022 into different adjusting locking holes 2021. This design allows for quick and reliable adjustment of the span between the two rocker arms, thereby adapting to large target objects of different sizes and shapes.

[0027] A sliding shaft 203 is provided below one end of the rocker arm 2. The rocker arm 2 is slidably connected to the track ring groove 101 through the sliding shaft 203. An electric cylinder 204 is provided below the other end of the rocker arm 2. The electric cylinder 204 extends to the outside of the rocker arm 2. A support foot 2042 is provided below the electric cylinder 204. A shock-absorbing spring 2041 is provided between the support foot 2042 and the electric cylinder 204. Metal balls are provided at the bottom of both the sliding shaft 203 and the support foot 2042.

[0028] In this embodiment, the electric cylinder 204 at the other end of the rocker arm 2 extends to the outside of the rocker arm, and the support leg 2042 at its lower end contacts the ground through the shock-absorbing spring 2041. The electric cylinder 204 can independently and precisely control its extension and retraction. On uneven outdoor ground, the system can dynamically compensate for ground undulations by adjusting the length of multiple electric cylinders in real time, so that the entire ring track system remains horizontal and stable. The metal ball bearings at the bottom of the support leg 2042 facilitate slight positional sliding during adjustment, reducing lateral stress.
