High Frequency Direction Finding Using Structurally Integrated Antennas on a Large Airborne Platform

Estimating the angle of arrival (AOA) of a high frequency (HF) signal, 2- 2 MHz, is challenging, especially if the antenna array is installed on a platform with dimensions on the order of one wavelength. Accurate AOA estimates are necessary for search and rescue operations and geolocating RF emitters of interest. This research examines the performance of a direction finding (DF) system using structurally ntegrated (SI) antennas installed on an airborne platform which allows the aircraft str...
