Embodiment Construction

[0026] Now in conjunction with embodiment, accompanying drawing, the present invention will be further described:

[0027] The structure of the invention integrates all subsystems of the radar in a square frame. The overall dimensions of the frame are: 4500 (length) × 2950 (width) × 500 (height), and the total weight is 2 tons.

[0028] In order to reduce costs and improve reliability, each A / D board, DC / DC power supply, and substation optical transceiver correspond to 16 transceiver components, so the traditional planar integration is changed to three-dimensional integration, that is, the radar frame is divided into front and rear compartments.

[0029] see figure 1 , the frame 1 is formed by riveting, and the partition in the middle is divided into two cabins. There are 640 transceiver components and antenna arrays 2 installed in the front cabin, which are irregularly distributed in a triangle shape, and the horizontal spacing of each module is 58.9 mm, and the vertical sp...

Abstract

The invention relates to a large-scale active phased array radar integrated structure, which adopts a layout form of arranging a front cabin and a rear cabin. The front cabin is used for installing a transceiving assembly and antenna dipoles. The rear cabin is used for installing other subsystems. In order to improve repeated positioning precision of the antenna dipoles, the dipoles are installed on the transceiving assembly, the front surface and the rear surface of the transceiving assembly are each provided with a positioning pin, the front positioning pin can ensure the repeated positioning precision of the antenna dipoles, and the rear positioning pin can ensure the blind matching precision of the transceiving assembly and a socket. In order to improve the maintainability of a radar, an antenna cover adopts a bidirectional sliding rail installation method and can be manually disassembled in the field. In order to improve the reliability of the radar, the glues pouring and reinforcement processing is carried out on the blind matching socket used for the transceiving assembly.

Description

technical field [0001] The invention belongs to the field of radar engineering and relates to the design of a complex phased array radar structure. The invention proposes solutions to the problems of difficulty in ensuring repeatability of large-scale phased-array radars, poor maintainability, and poor reliability of rectangular sockets used in large quantities, and can be applied to large-scale and complex phased-array radar structure designs. Background technique [0002] The new phased array radar is characterized by large volume, heavy weight, high antenna repeatability requirements, high system integration, and high system reliability requirements. The aforementioned requirements place high demands on the structural design. At present, phased array radars often install the modules of all subsystems of the radar in one plane, resulting in too high installation density of the modules, which is not conducive to heat dissipation; the blind-matching sockets connecting the t...
