( 2 ) when 37ghz and 94ghz radars detect clouds , the difference between the atmosphere and cloud attenuation and the large variety of radar reflectivity conduce the intension of the radar backscatter signals change . ( 3 ) for the thin cloud layer and low water content of cloud , 37 - ghz radar backscatter signals are not as good as 94 - ghz radar , that is to say that the 94ghz radar has better capability in thin clouds detection 本工作得出如下结论: ( 1 )大气气体的微波吸收在测云波段产生明显的衰减,其中水汽衰减效应变化很大;即将上天的空间94ghz测云雷达必须有水汽衰减订正方案; ( 2 ) 37ghz和94ghz雷达测云,由于大气和云衰减不同和雷达反射率的很大差异,导致雷达回波信号强弱不同; ( 3 )对云层较薄、含水量较少的云,在不计雷达参数的情况下, 37ghz雷达回波信号不如94ghz测云雷达,也就是说94ghz对薄云有更强的探测能力;对云层较厚、含水量大的云,由于强衰减的作用, 94ghz雷达回波信号小于37ghz雷达; ( 4 )从大气衰减的不利因素方面考虑,空间94ghz雷达测高层薄云的效果最好;测低层薄云时需要考虑气体衰减订正;因浓厚云的强衰减作用,探测其中下部的能力大大减弱,不仅要进行衰减订正,而且要借助其他信息来反演整个云层的含水量垂直分布; ( 5 )为了获得从极薄到极浓厚云的垂直分布探测能力,未来测云雷达系统最好采用双波长甚至三波长(如94 、 37和13ghz ) 。 |
