摘要
近年国际上相控阵技术在大气探测领域中的应用有了重要进展,成为雷达气象学研究的又一新热点,并可能成为今后天气雷达发展的重要方向。介绍了相控阵技术在气象探测中应用现状和研究进展,以及近年在气象应用中所获得的最新研究成果,展望了相控阵技术的应用前景,进一步讨论了开展相控阵技术研究所面临的技术挑战和未来发展的方向。为我国开展相控阵天气雷达的研制提供参考。
In recent years the study of phased array technology for detecting atmosphere has been made great progress, and become a popular aspect of radar meteorology. Phased array weather radar has the characteristics of less scanning time, higher resolution than conventional Doppler weather radar both in time and space. It also has the capability of real-time detection and be able to obtain high quality data. With these characteristics, it will be- come a ＂hot point＂ in the field of weather detection radar. This paper presents detecting technology status of phased array and its evolvement, and new application for detecting atmosphere of phased array technology, and prospects future meteorological application of phased array detecting technology. At a more advanced stage, the upcoming technology challenges and the future development trends are addressed, being useful to the study of phased array weather radar in China.
