| Abstract | The vortices generated by large aircraft can create dangerous encounter situations with other airplanes as a result of their slow dissipation rates or in conjunction with unfavorable meteorological conditions that prolong their presence over a runway. Active and passive remote sensing systems were assessed to determine the feasibility of detecting aircraft trailing vortices using instrumentation on-board an aircraft. It was found that a modification of the front-end receiver of a 10 GHz weather radar system or a change of frequency to 35 GHz may allow vortex identification over a range of several kilometers. The CO2 laser coherent Doppler radar technique and passive radiometric techniques show considerable promise. |
