- 摘要:
- 信号处理器是天气雷达系统中数据采集和处理的重要部件,直接影响雷达对天气过程探测的准确性。为提高国产DRSP信号处理器输出的回波数据质量,成都锦江电子系统工程有限公司研发了随机相位编码功能。借助中国气象局在三亚天气雷达站开展的数据质量提升试验,通过设计合理的试验方法,验证了国产DRSP信号处理器的随机相位编码功能。结果表明:(1)国产DRSP信号处理器具有与RVP900相当基本数据处理功能;(2)国产DRSP信号处理器中随机相位编码功能有效消除二次回波及其造成的“马赛克”现象;(3)采用时效性较高的双重频模式,随机相位编码功能同样能达到较好的处理效果,提升回波数据质量;(4)该试验的设计准确客观,利于后续功能对比提供重要参考。经以上试验,有助于实现国产DRSP信号处理器对进口RVP900信号处理器的替换,并推进雷达关键部件的国产化进程。
- Abstract:
- Signal processor is an important part of data acquisition and processing in weather radar system, which directly affects the accuracy of weather process detection by radar. In order to improve the quality of echo data output by domestic DRSP signal processors, Chengdu Jinjiang Electronic System Engineering Co., Ltd. has developed a random phase coding function. In this paper, the random phase coding function of domestic DRSP signal processor is validated by means of the data quality improvement test carried out by China Meteorological Administration at Sanya Weather Radar Station and by designing reasonable test methods. The results show that:(1)The domestic DRSP signal processor has the same basic data processing function as RVP900.(2)The random phase coding function in the domestic DRSP signal processor can effectively eliminate the second trip echo and the "mosaic" phenomenon caused by it.(3)The dual-frequency mode with high timeliness can also achieve better processing effect and improve the quality of echo data.(4)The design of the experiment is accurate and objective, which is helpful to provide important reference for the follow-up functional comparison. Through the above tests, it is helpful to replace imported RVP900 signal processors with domestic DRSP signal processors, and to promote the localization process of radar key components.
