The second method is to structure a toeplitz matrix to approach the toeplitzed signal subspace under the rule of mimimum power of noise, when the algorithm is converged, the structured toeplitz matrix is a full rank matrix, the angle information of target are all reserved and the influence of noise is minimum at this time.

第二种改进的方法是在噪声功率最小约束准则下构造一个Toeplitz矩阵，去逼近Toeplitz化后的信号子空间，当算法收敛时，所构造的Toeplitz矩阵是一个满秩矩阵，它既无损的保留了信源的角度信息又使噪声对DOA估计的影响最小。

The release of the footage is a stark contravention to the international law .the Taliban is exploiting the solder to propagate itself .we are delightful to see the solder unharmed , and we will try every possible means to sure his release in safty and security .we are using all resouse available to archieve this targe , and we are contacting the locals by every possible channels ,for instance we have leafleted a telephone number to the afghanistans so that any of them who knows the whereabouts of the captured solder can contact us .

播放这段视频明显地违备了国际法。这是塔利班在利用这名士兵来达到自己的宣传目的。看到这名士兵身体似乎无恙，我们感到很高兴，我们将尽一切可能使他毫发无损的、安全的获释。我们正在用可利用的一切资源来达到此目的，我们正在用可利用的一切手段与当地人取得联系。例如，我们用传单公布了一个电话号码，以方便那些可能会知道这名士兵被押地点的阿富汗人与我们取得联系。
