In order to obtain a reliable estimation of the number of the incident signals when the signal-to-noise(SNR) is low or the sources are spatially adjacent in complex electromagnetic environment,a pseudo-data matrix capable of separating cyclic statistical coherent signals is founded via temporal averaging,and the information criterion is also brought in to propose a novel source enumeration method.
为了实现低信噪比条件下以及复杂电磁环境中对阵列接收信号源个数的有效估计,利用雷达和通信信号普遍具有的循环平稳特性,借助时域平滑的思想建立了能够分离循环统计相干信号的伪数据矩阵模型,并将基于信息论准则的源个数估计方法引入对循环平稳信号的处理中,提出了一种环境适应能力更强、性能更优的循环平稳信号源个数估计方法,仿真实验验证了新方法的优良性能。
