摘　　要：提出基于相关的旋转干涉仪二维方向估计方法。传统方法仅利用相位差的最大值和最小值,由于没有利用全部信息,在有噪声的环境中,获得的方向估计精度不高。使用相关的方法,利用全部相位差信息,对方向的估计更为精确。通过计算机仿真实验验证了该方法的有效性及高精度特性。A bi-dimension direction estimation method based on correlated rotational interferometer is proposed. In the noise environment, estimation precision of direction finding is worse for just the maximum and minimum of phase difference is used without anyother information. All phase difference information by correlation is used in the proposed method which could get higher direction estimation. It is prove, d with simulations that the method is effective and could get high precision.
