Abstract :
The paper considers a direction finding system consisting of two squinted antennas that functions both as an interferometer and as an amplitude comparison system. The interferometer spacing is such that ambiguities exist, and a statistical analysis is used to describe the performance of using the amplitude based angle to select the correct ambiguous angle of incidence. The statistical analysis is at the system level so that no particular hardware implementation need be considered
