Direction Finding (DF) is a critical technology across the spectrum of Electronic Warfare (EW) applications and domains, with increasing demands for accuracy even as the electromagnetic spectrum becomes more congested. The goal of this presentation is to provide an understanding of how radio frequency DF systems work in both communications and radar applications.
Starting with amplitude and phase comparison DF systems, their operation, accuracy, and applications will be explored. This will be followed by a similar discussion for Time Difference of Arrival (TDOA) and Frequency Difference of Arrival (FDOA). DF system components are also discussed, with a focus on the antenna, arrays, and DF specific electronics. This understanding of the system architecture and DF methods is then used to evaluate their accuracy and how that is measured. This presentation will conclude with an overview of current DF methods for multiple simultaneous signals, such as Multiple Signal Classification (MUSIC) and Estimation of Signal Parameters via Rotational Invariance Technique (ESPIRIT).
