Design of an Electronically Steered Antenna Array in the X band

Abstract

Nowadays, unmanaged aerial vehicles (UAVs) are rapidly expanding to commercial or public sector. These vehicles, called drones, should be very dangerous, in case of collision with planes. Typical primary surveillance radars are not able to detect because radar cross section (RCS) of UAVs is out of resolution of the radar. It is necessary to develop new type of radar to detect and localize these small UAVs. Our project is focused on development of the new type of radar able to detect these UAVs. The paper deals part of our project, analysis and design of the new type of transmitter electronically steered array for FMCW radar, using phased array antenna in the X band. Finally, the designed array and it´s simulations using ASA Radom are presented.
