Description

Technical Field

[0001] This utility model relates to the field of radar receiver testing technology, and specifically to a comprehensive testing device for radar receivers. Background Technology

[0002] The radar receiver is a key component of a radar system. Its main task is to amplify, transform, and process the echo signals received by the antenna. These signals are usually accompanied by noise, clutter, and interference. The radar receiver needs to pre-select, amplify, filter, and demodulate these signals. Radar receivers can be classified into single-channel receivers, three-channel receivers, and multi-channel receivers according to different configurations. Single-channel receivers are commonly used in two-coordinate radars, three-channel receivers are commonly used in monopulse tracking radars, three-coordinate radars, and phased array radars, and multi-channel receivers are used in phased array radars that employ digital beamforming technology.

[0003] Comprehensive testing of radar receivers is a crucial step in ensuring the performance and reliability of radar systems. Testing typically includes evaluating aspects such as receiver sensitivity, dynamic range, operating bandwidth, intermediate frequency selection, filtering characteristics, and operational stability. Currently, when testing the operational stability of radar receivers, vibration testing is often conducted using vibration mechanisms. However, most vibration mechanisms operate at a fixed frequency, making frequency adjustment impossible and increasing the data error range. Therefore, a comprehensive testing device for radar receivers is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a comprehensive testing device for radar receivers to solve the problem that most vibration mechanisms have fixed vibration frequencies, making it impossible to adjust the vibration frequency and thus increasing the error range of the data.

[0005] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0006] A comprehensive testing apparatus for a radar receiver, comprising:

[0007] A fixed cover, which is open on one side, has a rotating plate on the outside of the fixed cover, and the rotating plate rotates relative to the fixed cover;

[0008] A support assembly is disposed at the opening end of the fixed cover and is used to provide support for the fixed cover. The support assembly includes a fixing seat, and the fixing seat is disposed at the opening end of the fixed cover.

[0009] A connecting component, disposed inside the support component, is used to fix the position of the receiver. The connecting component includes a mounting component, a fixing rod, and a fixing strip. The mounting component and the fixing strip are disposed at both ends of the fixing rod, and the fixing rod slides inside the fixing seat. The fixing strip has a sliding groove inside.

[0010] A rotating assembly, disposed within a support assembly, provides power to the connecting assembly. The rotating assembly includes a support member connected to a fixed base. A fixed shaft is located inside the support member, perpendicular to the direction of movement of the fixed rod. One end of the fixed shaft passes through the fixed base and is equipped with a motor connected to the fixed base. The other end of the fixed shaft is equipped with a fixed disc. A connecting shaft is located on one side of the fixed disc and slides within a sliding groove. A guide groove is formed on the fixed disc relative to the fixed rod. An adjusting component for adjusting the vibration frequency is located within the guide groove. The adjusting component includes a threaded rod disposed within the guide groove, with its axis parallel to the direction of movement of the fixed rod. A sliding block is located on the outer side of the threaded rod, moving relative to the fixed disc and connected to the connecting shaft.

[0011] Furthermore, the outer side of the fixing cover is provided with multiple connecting pipes, which are connected to the fixing cover.

[0012] Furthermore, the fixing base is hollow inside, and a guide tube is provided inside the fixing base. Multiple connecting rods are provided inside the fixing base, and the connecting rods pass through the fixing base on the side opposite to the fixing cover. A spring is sleeved on the outside of the connecting rod.

[0013] Furthermore, the mounting component is disposed inside the fixed cover, and the mounting component is connected to the connecting rod, wherein the moving direction of the fixed rod is parallel to the height direction of the fixed base.

[0014] The beneficial effects of this utility model are as follows:

[0015] This invention, through the arrangement of rotating components and adjusting parts, achieves adjustment of the vibration frequency of the mounting component during testing by cooperating with a fixed shaft, fixed disc, guide groove, connecting shaft, threaded rod, and sliding block. This avoids the problem of a fixed vibration frequency in the vibration mechanism, which would prevent adjustment and reduce the error range of the data.

[0016] By setting up support and connecting components, the cooperation of the fixed seat, connecting rod, spring, mounting part and fixed rod can guide the movement direction of the mounting part during use, prevent the fixed rod from separating from the fixed seat during the test, and ensure the stability of the test.

[0029] like Figures 1 to 6 As shown, a comprehensive testing device for a radar receiver includes: a fixed cover 1, which is open on one side, and a rotating plate 101 is provided on the outside of the fixed cover 1, which rotates relative to the fixed cover 1; a support assembly 2, which is disposed at the open end of the fixed cover 1 and is used to support the fixed cover 1; a connecting assembly 3, which is disposed inside the support assembly 2 and is used to fix the position of the receiver; and a rotating assembly 5, which is disposed inside the support assembly 2 and is used to provide power to the connecting assembly 3. Specifically, when the receiver needs to be tested, the receiver is first connected to the connecting assembly 3. After the connection is completed, the fixed cover 1 blocks the receiver to prevent the receiver from separating from the connecting assembly 3 and causing damage during the test. Then, the receiver is comprehensively tested by the cooperation of the rotating assembly 5 and the connecting assembly 3. The receiver is prior art and will not be explained in detail here.

[0030] like Figures 1 to 6 As shown, the outer side of the fixed cover 1 is also provided with multiple connecting pipes 102, which are connected to the fixed cover 1. Specifically, the rotating plate 101 is provided with an observation window to facilitate the viewing of the receiver's status during testing. The outer side of the fixed cover 1 can be equipped with simulation components according to testing requirements. The added simulation components can be placed inside the fixed cover 1 through the connecting pipes 102, so that the simulation components, together with the connecting components 3, can test the receiver under different operating conditions, such as temperature, humidity, and vibration, to test the comprehensive performance of the radar receiver under these conditions.

[0031] like Figures 1 to 6As shown, the support component 2 includes a fixed base 201, which is located at the opening end of the fixed cover 1. The fixed base 201 is hollow inside and has a guide tube 202 inside. Multiple connecting rods 203 are provided inside the fixed base 201, and the connecting rods 203 pass through the fixed base 201 on the side opposite to the fixed cover 1. A spring 204 is sleeved on the outside of the connecting rod 203. Specifically, the connecting rod 203 can be cylindrical, hexagonal prism, or elliptical prism. The connecting rod 203, together with the fixed base 201, guides the movement direction of the connecting component 3, ensuring the accuracy of the movement direction of the connecting component 3 during the test. While guiding the connecting component 3, the spring 204 provides a reset force to the connecting rod 203 and limits the movement distance of the connecting rod 203 to prevent the connecting rod 203 from separating from the fixed base 201 during the test.

[0032] like Figures 1 to 6 As shown, the connecting component 3 includes a mounting member 301, which is disposed inside the fixed cover 1 and connected to the connecting rod 203. A fixing rod 302 is provided on the side of the mounting member 301 relative to the fixed base 201, passing through the fixed base 201 and moving relative to the fixed base 201. The direction of movement of the fixing rod 302 is parallel to the height direction of the fixed base 201. A fixing strip 303 is provided at the other end of the fixing rod 302, with a sliding groove 304 inside the fixing strip 303. Specifically, the fixing rod 302 can be in the shape of a quadrangular prism, an elliptical prism, or a hexagonal prism to prevent the fixing rod 302 from rotating relative to the mounting member 301 during testing, ensuring the accuracy of the angle during the movement of the fixing strip 303. The mounting member 301 and the receiver can be connected by bolts or clips. Multiple mounting slots are provided on the outer side of the mounting member 301, allowing for selection of a suitable mounting slot based on the receiver's size during testing, ensuring test compatibility.

[0033] like Figures 1 to 6As shown, the rotating assembly 5 includes a support member 504, which is connected to the fixed base 201. A fixed shaft 505 is located inside the support member 504 and is perpendicular to the moving direction of the fixed rod 302. One end of the fixed shaft 505 passes through the fixed base 201 and is equipped with a motor connected to the fixed base 201. The other end of the fixed shaft 505 is equipped with a fixed plate 501. A connecting shaft 502 is located on one side of the fixed plate 501 and slides within a sliding groove 304. A guide groove 503 is provided on the side of the fixed plate 501 opposite to the fixed bar 303. The guide groove 503 also contains a groove for adjusting the vibration frequency. The adjusting component 4 specifically includes a support component 504 that provides support for the fixed shaft 505 to prevent the fixed shaft 505 from swaying and ensure the stability of the fixed disk 501 during rotation. The connecting shaft 502 is located on one side of the fixed disk 501, so that as the connecting shaft 502 rotates with the fixed disk 501, it works with the fixing bar 303 to drive the fixing rod 302 and the mounting component 301 to move up and down, thereby enabling the testing of the receiver. The end of the connecting shaft 502 is provided with a stop block, which restricts the position of the connecting shaft 502 relative to the fixing bar 303, preventing the connecting shaft 502 from separating from the fixing bar 303 during the test and ensuring the stability of the receiver test.

[0034] like Figures 1 to 6 As shown, the adjusting component 4 includes a threaded rod 401, which is disposed inside the guide groove 503. The axis of the threaded rod 401 is parallel to the moving direction of the fixed rod 302. A sliding block 402 is provided on the outer side of the threaded rod 401. The sliding block 402 moves relative to the fixed plate 501 and is connected to the connecting shaft 502. Specifically, one end of the threaded rod 401 passes through the fixed plate 501, and a connecting groove is provided at the end of the threaded rod 401. The connecting groove is compatible with tools such as an Allen wrench or a screwdriver, so that the threaded rod 401 can be controlled by tools such as an Allen wrench or a screwdriver during use. The guide tube 202 guides the tools such as an Allen wrench or a screwdriver to ensure that the tools can be accurately inserted into the connecting groove. The threaded rod 401, together with the sliding block 402, adjusts the distance between the connecting shaft 502 and the center of the fixed plate 501, so that the receiver can be tested under different working conditions.
