为适应国防装备关键部件的国产化进程,选用2014年3～7月,在某型多普勒天气雷达上,国营第784厂生产的DRSP和进口RVP8两型信号处理器分别采集的基础数据,开展处理效果的回波形态结构对比,并引入段百分比、段偏差、段偏差百分比、段平均差及均方根误差进行定量分析,该方法可供类似试验参考.结果表明:两型信号处理器对回波形态结构处理效果基本相当;DRSP对于各区间数据处理效果的定量分析按优排序为速度、强度、谱宽;针对数据差异集中区间和谱宽产品,包括信号处理器参数配置等方面展开优化,进一步提高国产器件的精度.

In order to adapt to localization process of the key components of national defense equipments.During March to July in 2014,a large amount of basic data has been collected by DRSP and RVP8 installed in a certain type of doppler weather radar.Using the above data,contrast analysis of their echo morphological structure was carried out,and quantitaive analysis was done through the introduction of segment percentage,segment deviation,segment deviation percentage,segment mean difference and root mean square error.The contrast of echo morphological structure showed that DRSP and RVP8 had almost consistent abilities.But quantitative analysis which can be used for reference in the similar test showed that the greatest effect of DRSP was the ehco of radial velocity,the second was the ehco of reflectance factor and the worset was spectral width.By optimizing the various aspects including parameter configuration for segments of the concentrated differience and spectral width,the precision of DRSP will be further improved.
