对2维doa进行估计，在不同的快拍数情况下，BPSK信号的经典MUSIC估计比单频信号的经典MUSIC估计方法均方根误差性能更好-On 2 d to estimate doa. In different fast take several cases, BPSK signal of classical MUSIC estimate than single frequency signal of the classical MUSIC estimation method root mean squ

存在阵元位置误差时的信号DOA估计，阵列误差，有源校正-When there is a sensor position errors DOA Estimation array error, active correction

米波雷达低仰角DOA估计及阵列通道误差校正-VHF radar and an array of low-elevation DOA estimation error correction channel

正确率可以达到98％，通过虚拟阵元进行DOA估计，预报误差法参数辨识-松弛的思想。- Accuracy can reach 98 , Conducted through virtual array DOA estimation, Prediction Error Method for Parameter Identification- the idea of relaxation.
