中文摘要:
      研究了云雨质点对雷达波的相干散射,从而推得比较普遍的雷达气象方程。旧的雷达气象方程是新方程在云雨质点互相独立时的特殊表现形式。对新方程作了一些讨论,发现旧方程之所以在某些方面与实验不符,可能是因为忽略了相干散射作用的缘故。
英文摘要:
      Attention has becn paid to the fact that goouping associatiop between particles exists in clouds as well as in rain.Coherent scattering of radar waves from cloud and rain drops dependent to each other has been evaluated and a new radar equation derived.The new equation involves the old one as its special form in the casc of incohercnt scattering.It is found that the effect of coherent scattering in some cases is not quite small and should not be neglccted.
