THE DISTORTION CUMULONIMBUS PRECIPITATION OBSERVED BY RADAR,
Abstract
The intensity of the returned signal at any point on a radar display is due to the backscattering from all the elements within the volume of the pulse. The depth of the pulse in range is only small, but its width both in azimuth and elevation is proportional to range, and significant power can be received from well outside the half-power points. This integration over the pulse volume produces a distortion of the intensity pattern, whose effect increases with range. In particular, strong gradients of intensity such as occur at the edges of cumulonimbus precipitation will be smoothed out, so that echo will be displayed outside the true edge of the precipitation.
