| Abstract: |
| The 38th Research Institute of China Electronics Technology Group Corporation(CETC) has developed the first domestic high-end DSP named HunXin-1 Chip（BWDSP100）. In order to break the monopoly of foreign high-end chips,the application of the domestic digital signal processor in weather radars is significant. With fast Fourier transform(FFT) method, Pulse Part Processing(PPP) method and batch method,the weather radar echo parameters estimation is accomplished based on the self-developed software environment. The HunXin-1 Chip with four cores of parallel processing ability is used in the hardware to complete three main processing modes efficiently.And it is demonstrated that HunXin-1 Chip is better than foreign high-end signal processor in speed and accuracy.Application of domestic signal processor in weather radars will highlight its superior practical value. |
