在DOA估计中，实际测量和理论肯定存在误差，比如通道误差，阵元位置误差，我们提出一种toplitz的预校正方法。-In the DOA estimate, the actual measurement and theory certainly exist errors, such as channel error, array (position errors, we put forward a kind of toplitz or calibration methods.

对于样本数较多的数组，自动分为校正集和预测集的两个方法。-For larger sample size of the array, automatic calibration set and prediction set into two methods.

上传代码都是MATLAB关于music算法的内容，其中包括针对阵列幅相误差进行线阵校正的经典NSF方法，music-capon最小方差法，music算法估计声源方位谱。-Upload code are MATLAB algorithm on music content, including amplitude and phase errors for the array line array calibration method NSF classical, music-capon minimu

稳健的波束形成算法，能够进行旁瓣控制，性能稳健，对角度对不准及阵列校准误差存在情况下，仍有较好的波形-Waveform robust beamforming algorithm, can be sidelobe control, robust performance, under the angular misalignment and the presence of an array of calibration errors, there are still good

最小二乘ESPRIT (LS-ESPRIT)的Matlab实现与相关性能分析，直接由特征值确定DOA，大大减少了计算量；不需要精确知道阵列流型向量，对阵列校准要求不严格。-analysis and performance to LS-ESPRIT achieved by the Matlab, DOA value is determined directly by the characteristics, greatly reducing the amount of calculation d
