Abstract

Angle-of-arrival (AOA) estimation algorithms for electronic surveillance systems are often required to be accurate, computationally fast and implemented using sparse large aperture arrays. This paper considers the speed and accuracy of the SODA and SBI interferometers [1, 2] in the context of sparse large aperture arrays and compares their performance to the conventional phaseshift beamformer and MUSIC algorithm. The performance of the algorithms will be compared through simulation and verified using experimental data.
基于稀疏大孔径阵列的快速AOA估计
电子监视系统的到达角(AOA)估计算法通常要求准确、计算速度快,并使用稀疏大孔径阵列实现。本文考虑了SODA和SBI干涉仪在稀疏大孔径阵列下的速度和精度[1,2],并将其性能与传统的移相波束形成器和MUSIC算法进行了比较。通过仿真比较算法的性能,并用实验数据进行验证。
