摘　　要：机载雷达可以方便地跟踪观测对象，并且可以观测有些地基雷达较难观测的区域（ 如海洋） ，因此近年来在大气遥感领域得到越来越广泛的应用。由于应用的需要，机载雷达使用的一般为 Ｘ 波段或 Ｋｕ 波段的频率，而该波段的电磁波穿过雨区时会受到衰减，需寻找算法进行订正。对于单束单频雷达，ｋ Ｚ 和ｋ Ｚ Ｓ算法具有很好的应用前景。将ｋ Ｚ、ｋ Ｚ Ｓ应用到在西太平洋进行的国际大型科学考察实验 Ｔ Ｏ Ｇ Ａ／ Ｃ Ｏ Ａ Ｒ Ｅ 中１９９３ 年１月和２ 月间取得的机载雷达（ 和星载雷达频率相近） 实测数据进行雨空间分布的研究。The airborne radars can easily follow the observed phenomena and allow to scan meteorological systems in places where ground_based radars are not easy to operate and they are progressively used in meteorological studies. Due to the requirements of the applications. airborne radars use an X_band or Ku band frequency. However, the electromagnetic wave on the frequency is attenuated through rain, thus algorithms should be studied to correct for the attenuation effect. For the single beam_single frequency rain radar, kZ and kZS algorithms demonstrate a promising interest for application. This paper applies kZ and kZS algorithms to the airborne data gathered in January and February 1993 during the TOGA/COARE experiments and studies the rain structure.
