Abstract

The invention discloses a digital array weather radar signal processor based on a PCIE optical fiber acquisition card. The digital array weather radar signal processor comprises a signal processing unit; the signal processing unit comprises a signal receiving module, a signal storage module, a signal analysis module, a pulse compression module, a filtering module, a signal processing module, a quality control module and a parameter configuration module. The processor solves the problems that the difficulty of the research and development and simulation debugging of a signal processing algorithm are large, and the improvement of the signal processing algorithm and function upgrading is difficult; and a universal server is adopted as a hardware platform of the signal processing unit, the operation speed is high, the expansibility is high, software design is adopted, the function of a radar system is improved or expanded through software reconstruction and continuous improvement, and rapid multi-beam signal processing of the digital array weather radar is realized.

Description

technical field [0001] The invention relates to the field of digital array weather radar, in particular to a digital array weather radar signal processor based on a PCIE optical fiber acquisition card. Background technique [0002] One advantage of digital array radar is that it can acquire echo data on multiple beams (elevation angles) in a very short time, so that the acquired data has extremely high time resolution. Before the improvement, the signal processing adopts the CPCI general-purpose processing extension, and the IQ data adopts parallel data transmission, and the parameters of intensity Z, speed V and spectrum width W are output through the standard network port. The design and development time is relatively early, and it is difficult to increase, improve algorithm; [0003] After the signal processing is improved, the hardware platform of the high-performance server based on the PCIe fiber optic acquisition card is adopted, and the whole software is processed. ...
