| 摘 要： | 针对共形天线阵列流形的多极化特点,建立了锥面共形阵列天线导向矢量的数据模型。通过合理的阵元排列结构设计,推导了锥面共形阵列天线信源解相干的空间平滑算法,解决了ESPRIT(estimation of signal parameters via rotational invariance technique)算法多信源方位估计的参数配对问题,最终给出了锥面共形阵列天线相干信源盲极化波达方向(direction of arrival, DOA)估计算法。该算法利用锥面共形载体的单曲率特性,结合ESPRIT算法参数估计的特点,在盲极化条件下实现了相干信源的高分辨DOA估计。Monte Carlo仿真实验验证了算法的有效性。

| Abstract: | In view of the polarization diversity of conformal array antennas,the array manifold model for conical conformal array is established.With the help of special element arrangement,the spatial smoothing technology in conical conformal array antenna is developed,and the parameters pairing method of estimation of signal parameters via rotational invariance techniques(ESPRIT) is given when direction of arrival(DOA) of multiple sources are estimated.On this basis,a blind DOA estimation algorithm of coherent sourc... |
