摘要
本文针对宽频段窄带相干信号源,充分利用多重信号分类和旋转不变两大技术,结合一定的 时域信息,提出了一种高精度的信号频率和波达方向同时估计方法.该方法通过构造平滑波 达方向矩阵进行参数估计,无需搜索过程和配对处理.计算机仿真验证了本文所提出方法的 有效性.
Based on the MUSIC and ESPRIT techniques and using the signal temporal informati on,a new method with high precision is presented for simultaneous estimation of frequency and direction of arrival (DOA) of spatial coherent signal sources over a wide frequency band. By means of forming a so called smoothed DOA matrix,the estimated parameters of frequencies and DOAs are paired automatically.Simulatio n results show that the proposed method is effective.
