This paper points out that we can use the density function of the Gaussian distribution to set a thinned array, extending the covariance matrix will advance the gain clearly.

提出利用高斯随机分布的密度函数设置稀疏阵列，在稀疏阵列得到的协方差矩阵经扩展后，增益有了明显的提高。

This approach, unlike the conventional statistical techniques requiring for a covariance matrix of sample, is based on direct spatial processing of the array data.

这种方法不同于传统的统计方法需要计算样本协方差矩阵的逆矩阵，而是基于阵列数据的一种直接计算方法。
