Abstract :
Conventional interferometric techniques used in electronic support (ES) systems are often limited to estimating the angle-of-arrival (AOA) of one narrowband radar signal at any given time. This paper proposes a simple, low-cost extension that enables these systems to estimate the AOA of two simultaneous narrowband radar signals using only two receivers.
