Description

technical field [0001] The invention relates to the development field of radar signal processors, in particular to a signal processor for Doppler weather radar. Background technique [0002] In the existing technology, the signal processing part of the radar is generally implemented by a dedicated DSP chip combined with an FPGA. Due to the high complexity of FPGA and DSP chip programming, it is more difficult to develop and simulate the signal processing algorithm, especially limited Due to the internal resources of the chip, it is difficult to improve the signal processing algorithm and upgrade the function in the later stage; and the radar signal processing part uses the dedicated differential bus or parallel data bus of the backplane to receive the IQ signal, and the data transmission rate is limited by the backplane bus rate. Contents of the invention [0003] In order to overcome the defects of the above-mentioned prior art, the present invention provides a signal pr...
