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 the acquisition of echo data on multiple beams (elevation angles) in a very short period of time, resulting in extremely high temporal resolution. Before the improvement, the signal processing adopts the CPCI general processing extension, and the IQ data adopts parallel data transmission. The parameters of intensity Z, speed V and spectral width W are output through the standard network port. The design and development time is earlier, and due to the limitation of hardware resources, 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 optical fiber acquisition card is adopted, and the whole s...
