Experiments with an experimental clear-air radar near an airport demonstrate that short range 10 cm radar can reliably detect and locate wingtip vortices shed by large jets. The radar was calibrated in both return power and velocity so that radar cross sections and velocity widths could be calculated. Histograms of radar cross section and a weighted spectral width parameter are presented for 44 vortex and 44 non-vortex cases. The non-vortex data was taken just before the vortex-producing aircraft entered the antenna beam. The time variation of these two parameters for one particular case is presented. Some arguments on the size of the return-producing portion of the vortex are presented. The expected maximum range of a radar similar to that used in this experiment is also presented.
