Abstract: Modern air traffic control systems in airports use high-speed ground tracking radars usually rotating at 60 rpm. The flow induced vibration and noise generation of the newly developed radar antennas are the two serious problems that jeopardise the successful deployment of the ground aircraft tracking systems. The present study is an attempt to understand the viscous flow characteristics around a typical radar antenna cross section via computations. After a steady-state validation of the computations, a parametric study of possible new shape designs for the antenna is discussed. Significant aerodynamic drag reductions via careful shape design of the antenna are possible.
