本文考虑使用智能天线系统来估计多个波的到达方向（DOA）。提出了一种基于支持向量回归的有效方法，该方法利用一族支持向量机来逼近阵列输出与未知平面波波达方向之间的映射关系。几个数值结果提供了所提出的方法的验证，考虑多个冲击波在无噪声和有噪声的环境。
In this paper, the use of a smart antenna system for the estimation of the directions of arrival (DOAs) of multiple waves is considered. An efficient method based on the support vector regression is proposed, in which the mapping among the outputs of the array and the DOAs of unknown plane waves is approximated by means of a family of support vector machines. Several numerical results are provided for the validation of the proposed approach, considering multiple impinging waves both in noiseless and noisy environments.
