| 摘 要： | 利用国内第一个网络化雷达试验平台的观测资料,基于网络化雷达反射率因子衰减订正算法,对观测数据进行衰减订正。并与单部雷达自适应约束算法和常州S波段雷达观测资料进行比较分析,结果显示订正方案合理。个例分析表明,经过雨区后单部雷达探测的回波强度较弱甚至探测不到,而网络化雷达可以利用多部雷达的共同观测,弥补单部雷达探测上的不足,体现出网络化雷达衰减订正的优势。

| Abstract: | By using the observation data from the first domestic networked radar test platform, and with the attenuation correction function for networked radar reflectivity factors, the attenuation correction was conducted on the observation data. Moreover, the comparison with the self-consistent method with constraint of single radar of Changzhou S band radar shows that the correction scheme is reasonable. The case analysis indicates that in remote rainy area, the single radar detection is weak or even lacks meteorological echos. On the contrary, the networked radar system can make use of common observations from multiple radars to make up for the shortage of single radar observation, and manifests the advantage of attenuation correction. |
