中文摘要:
      本文介绍了使用国产711,713雷达,利用雷达偶极子技术在北京市上空进行大气湍流扩散观测的结果.初步解决了有关的理论和技术难点.这种方法具有操作简便、节省人力物力等优点,可在水平距离10公里内测定大气边界层扩散的状况.
英文摘要:
      This paper discusses the experimental data which collected in a turbulent diffusion experiments conducted in the boundary layer over Beijing by using the technique of radar-chaff.The carbon wire(diameter:8 μ; resistivity:1.7×10-3 ohm.cm) was used as the meterial of chaff; and the echo signal was detected by the weather-radar of modal 711(3cm) and model 713(5cm).Theoritical and technical problems concerned with the Radar-chaff technique have been analysed.It is evident that the method has advantages of simplicity and man-power and material saving.The behavior of turbulent diffusion could be measured within the range of 10 km.
