Software secondary radar based on general server platform

Abstract

The invention discloses a software secondary radar based on a general server platform. The software secondary radar comprises a transceiving and processing extension and a data processing server, wherein the transceiving and processing extension comprises a transmitter, a receiver and a digital intermediate frequency processing module; the data processing server comprises a signal processing unitand a data processing unit; the data processing server is an X86 architecture universal server, adopts an open source Linux operating system and has at least two CPUs, and each CPU has a plurality cores; and a PCIE optical fiber card is installed inside the data processing server, the digital intermediate frequency processing module and the data processing server are each internally provided withone or more optical fiber interfaces, and data transmission between the digital intermediate frequency processing module and the data processing server is conducted by adopting high-speed optical fibers. The software secondary radar improves the integration degree of the overall equipment of the radar, simplifies internal signal interfaces, reduces the cost and maintenance fee of the entire radar,and facilitates the research, development and simulated debugging of a signal processing algorithm of the secondary radar.

Description

Technical field [0001] The invention relates to the technical field of air traffic surveillance radars, in particular to a software secondary radar based on a general server platform. Background technique [0002] At present, the secondary radars of domestic and foreign manufacturers generally consist of antennas, turntables, transmitters, receivers, recorders, and track processing computers. Among them, the receiver and the recorder use the dedicated differential bus or parallel data bus on the backplane for data transmission; the recorder is generally implemented by FPGA, DSP, and embedded single-board computer. The signal processing algorithm of the secondary radar needs to be in PFGA and DSP. The signal processing algorithm includes amplitude and phase correction, modulus, anti-narrowing, sidelobe suppression, and pulse front extraction; the track processing computer performs track processing on the data processed by the signal processing algorithm, and the track processing ...
