Cascade AOA Estimation Technique Based on Uniform Circular Array
Tae-yun Kim, Dongbin Lee, Suk-Seung Hwang · 2020
The Angle-of-Arrival (AOA) information of various signals can be collected by employing planar array antennas such as Uniform Rectangular Array (URA) and Uniform Circular Array (UCA) installed in a satellite. In this paper, we introduce the cascade AOA estimation algotithm consisting of CAPON and Beamspace MUSIC based on UCA, which has good performance for estimating AOAs of adjacent signals. In addition, we provide the computer simulation result for illustrating the performance of the suggested technique.
