Ｅ Ｓ Ｐ Ｒ Ｉ Ｔ 算法是一种快速的高分辨率方向估计方法，但它是一种一维估计方法，不能直接推广到二维方向估计。本文在 Ｅ Ｓ Ｐ Ｒ Ｉ Ｔ 的基础上，针对一种特定的阵列结构，提出了一种计算量很小的二维估计方法——二维虚拟 Ｅ Ｓ Ｐ Ｒ Ｉ Ｔ，它的计算量同一维 Ｅ Ｓ Ｐ Ｒ Ｉ Ｔ 相当。
The E S P R I T algorithm is a fast high-resolution direction estimation method, but it is a one-dimensional estimation method that can not be directly generalized to two-dimensional direction estimation. In this paper, based on ESPRT, a two-dimensional virtual EPSRTI is proposed for a specific array structure, which has the same computational complexity The dimension E S P R I T is equivalent.
