The present work is dedicated to the modeling and evaluation of the radar signature of raindrops within wake vortices. This is achieved through the computation of the motion equation of raindrops within the wake vortex flow. Based on the inhomogeneous distribution of raindrops within wake vortices, the radar echo model is computed for raindrops in a given pulse resolution volume. Simulated Radar Doppler signature of raindrops within wake vortices is illustrated to be a potential criterion for identifying wake vortex hazard in air traffic control. The dependence of the radar signature on various parameters, including the radial resolution, antenna elevation angle, is also analyzed.
