Paper Abstract
The number of elements in a nonplanar antenna array, their respective farfield radiation patterns, the relative
spacing between the elements, and the signal processing approach determine the angle-of-arrival (AOA) estimation
performance for a direction finding (DF) system. Designing an airborne DF system becomes challenging
as the wavelengths of the signals of interest become large with respect to the host aircraft. Given an ensemble
of structurally integrated (SI) antennas designed using a discrete number of feed points, this paper presents an
analysis of AOA estimation as a function of the number of SI feed elements and their respective locations on a
large, three-dimensional aircraft model at HF (2-32 MHz). Empirical results for AOA estimation errors versus
the number and physical location of feed points are presented using the maximum likelihood method estimator
for 4 and 11 MHz signals of interest.
