Digital array radar optical fiber transmission network

Abstract

The invention provides a digital array radar optical fiber transmission network which is used to establish data communication between a digital T / R assembly and a signal processing assembly. The network comprises a single mode fiber connected to the signal processing assembly and an optical branching device connected to the established digital T / R assembly. The single mode fiber is used for sending a signal from the signal processing assembly to the branching device. The optical branching device divides the signal into several paths and then transmits to the digital T / R assembly. The single mode fiber and the optical branching device are connected in a jumper wire mode through one first optical fiber. The optical branching device and the digital T / R assembly are connected in the jumper wire mode through several second optical fibers. The transmission network adopts the single mode fiber and the optical branching device. Through an system improvement, ''one-to-many'' network interconnection is realized so that design cost and maintenance cost are greatly reduced, a signal phase jitter problem brought by multi-optical-fiber transmission is avoided and communication stability is increased.

Description

technical field [0001] The invention relates to the technical field of optical fiber transmission network design of digital array radar, in particular to a digital array radar optical fiber transmission network for establishing data communication between digital T / R components and signal processing combinations. Background technique [0002] In the digital array radar, the data communication rate between the digital T / R component and the signal processing combination is higher than 1.25Gbps / channel, and the traditional copper medium communication cannot meet the design requirements. Based on the special requirements of the application environment of digital array radar, such as the high-speed transmission of radar signals in the environment of military temperature, salt spray, mold, and sand dust, at present, multimode optical fibers are commonly used in engineering to realize data communication. At the beginning of the development of this technology, the transmission speed ...
