Abstract

The invention, which belongs to the radar structure design, relates to a structure of a T / R assembly of phased array radar solid state transmitter. The invention comprises a T / R assembly shell, an excitation source module with a sealed aluminum box, a receiving module with a sealed aluminum box, a first shielding washer, a second shielding washer, a sealing washer, and a shell cover; and a structure of a ''double peak'' sealing strip is formed by the first shielding washer, the second shielding washer, and the sealing washer. Therefore, problems on air tightness and strong electromagnetic interferences of the T / R assembly in the shell are solved; an adaptation capability of a radar environment is enhanced; and reliability during the using process of the radar can be effectively ensured.

Description

Technical field [0001] The invention relates to a T / R component structure of a phased array radar solid-state transmitter, belonging to radar structure design. Background technique [0002] The T / R component is the core part of the phased array radar antenna. The structural design of the T / R component shell should pay attention to the following issues: ⑴ The phased array radar requires high power density of the T / R component, and the components are medium and high-frequency. Circuits, DC circuits, and digital circuits coexist, and they are very tightly arranged, and there is strong electromagnetic interference; ⑵ T / R components usually use high assembly density technology, which will generate high heat; ⑶ Currently phased array radar uses T / The number of R components is increasing, and the weight and interchangeability of the T / R component housings are particularly prominent; ⑷Most radars are usually used in harsh natural environments, with high air tightness requirements, and T...
