    • A method for determination of precipitation types in the atmosphere is described, wherein an output signal, in particular a radar signal, having a transmitting frequency spectrum is transmitted, reflection signals formed by reflection of the output signals at precipitation particles at at least two atmospheric levels and having a reflection spectrum are detected, and wherein finally the characteristics of the reflection signals are analyzed.The method according to the invention is characterized in that on analyzing characteristics of the reflection signals a course of a difference frequency spectrum formed by transmission frequency and reflection frequency spectrum is analyzed resolved by altitude levels.
    • 描述了用于确定大气中的降水类型的方法,其中发射具有发射频谱的输出信号,特别是雷达信号,通过在至少两个大气压水平的沉淀粒子处的输出信号的反射而形成的反射信号 并且具有反射光谱,并且其中最后分析反射信号的特性。 根据本发明的方法的特征在于,在分析反射信号的特性时,通过高度水平分析由透射频率和反射频谱形成的差分频谱的过程。
