An Ultra-fast DOA Estimator with Circular Array Interferometer Using Lookup Table Method [PDF]

, 2015
The time-consuming phase ambiguity resolution makes the uniform circular array (UCA) interferometer not suitable for real-time direction-of-arrival (DOA) estimation. This paper introduces the lookup table (LUT) method to solve this problem.
