Embodiment 1

[0036] Such as figure 1 As shown, the integrated sub-array module includes a sub-array antenna 1, a multi-functional cold plate 2, a power distribution box 3, a sub-beam network 4, an active module 5, and an aperture conversion device 6; the sub-array antenna 1 is converted through an aperture conversion Device 6 is connected on one side of multifunctional cold plate 2 ( figure 1 The middle is the left side), the power distribution box 3 and the sub-beam network 4 are connected side by side on the other side of the multi-function cold plate 2, the active module 5 is located between the power distribution box 3 and the sub-beam network 4, the active module 5 The two sides are installed on the power distribution box 3 and the sub-beam network 4, and are electrically connected to the two; the sub-array antenna 1, the aperture conversion conversion device 6 and the active module 5 realize the connection of electrical signals through blind matching of cables and electrical connecto...

Embodiment 2

[0047] Such as figure 2 , image 3 As shown, a handle cable 7 is also included, and the power distribution box 3 is connected to the active module 5 through the handle cable 7 . It also includes a semi-rigid cable 8, and the sub-beam network 4 is connected to the active module 5 through a semi-rigid cable 8. The power distribution box 3 integrates a bus bar, uses the handle cable 7 to supply power to the active module 5, and integrates a sub-network inside the sub-beam network 4, and uses a semi-rigid cable 8 to provide local oscillator and clock signals to the active module 5.

[0048] The power distribution box 3 is in one-to-one correspondence with the connectors of the active module 5, and the sub-beam network 4 is in one-to-one correspondence with the connectors of the active module 5, and preformed cables (including the handle cable 7 and the semi-rigid cable 8) Connection solves the problems of many equipment connection cables and complicated interfaces.

Embodiment 3

[0050] This embodiment discloses a radar antenna array, which includes a plurality of integrated sub-array modules in Embodiment 2 above, and the plurality of integrated sub-array modules are connected in a matrix.

[0051] Based on the idea of ​​integrated design of structure and function, the radar antenna array is divided into multiple integrated sub-array modules with the same function and interface. Expansion can realize the modular combination design of the entire antenna array.

Abstract

The invention discloses an integrated sub-array module which comprises a sub-array antenna, a multifunctional cold plate, a power distribution box, a sub-beam network and an active module. The sub-array antenna is mounted at one side of the multifunctional cold plate, and the power distribution box and the sub-beam network are mounted on two sides of the other side of the multifunctional cold plate; two sides of the active module are respectively arranged on the power distribution box and the sub-beam network and are electrically connected with the power distribution box and the sub-beam network; the multifunctional cold plate is internally provided with a cavity filled with cooling liquid, and the active module is internally provided with a cold liquid pipeline which is in closed communication with the cavity; the subarray antenna and the active module are connected through an electric connector. The invention further discloses a radar antenna array plane adopting the integrated subarray module. The integrated subarray module and the radar antenna array plane have the following beneficial effects that an independent standard function module with mechanical, electrical, hydraulic and other interfaces is integrated; and the problems of large array surface equipment quantity, multiple connection interfaces, compact equipment installation space, difficulty in arrangement of a liquid cooling pipe network and the like are effectively solved.

Description

technical field [0001] The invention relates to the technical field of a radar system and an antenna, in particular to an integrated sub-array module and a radar. Background technique [0002] Phased array radar has the advantages of long detection distance, high precision, multiple function combinations, strong anti-interference ability, and high reliability. It is the main radar system at present. With the increase of the working frequency band, the radar antenna has the characteristics of high antenna unit density, large amount of equipment, and high array installation accuracy. At the same time, due to the variety of use environments, the layout of the antenna array is also varied. [0003] For example, the application number: 201910428171.7, a phased array antenna and its design and expansion method, a phased array antenna, is characterized in that it includes a sub-array module in a periodic array, and the sub-array module includes a plurality of antenna units, The t...
