Abstract

Future military aircraft and UAV´s require the installation of lightweight and low-cost Electronically Steerable Antennas (ESA) which are needed by high-performance Airborne Moving Target Indicator and Surface Moving Target Indicator radars. When these antennas are integrated into the skin of air vehicles, they are subject to unsteady aerodynamic loads. Mechanical forces and these aerodynamic loads will cause deformation of the antenna surface. In this paper the effects of vibrations on Direction of Arrival a.re investigated.
