Abstract : An apparatus for counting the number of passages through some given level by the envelope of the radar echo from a cloud of moving scatterers is examined theoretically. It is shown that the number of times the envelope passes through the average value is proportional to the root mean square of the projections of the relative or absolute speeds of the scatterers in the scattering volume onto the beam axis, depending on whether conventional or Doppler radars are used. During the investigation of wind variations, the number of these passages is proportional to the mean wind speed in the scattering volume. The effect of averaging in the scattering volume upon the energy spectrum of wind variations is also considered. (Author)
