研究了和差复合共阵欠定波达方向估计精度。本文研究了将和差共阵概念与和差共阵概念相结合来进一步提高自由度的方法，称之为“和差复合共阵”，并对其波束形成性能进行了评估。我们的目的是调查，如果和差复合阵列也适用于欠定DOA估计问题。通过计算机模拟DOA估计，对所提出的阵列配置的性能进行了评估。
This paper studies underdetermined direction of arrival (DOA) estimation accuracy by sum and difference composite co-array. We have studied to further enhance the DOF by combining the concepts of the sum co-array and the difference co-array, which is called “sum and difference composite coarray”, and evaluated its beamforming performance. We aim at investigating if the sum and difference composite co-array also works well for underdetermined DOA estimation problems. Performance of the proposed array configuration is evaluated through computer simulation of DOA estimation.
