Abstract： Addressing issues such as installation errors in antenna positions，mutual coupling between antenna elements，and other errors that affect direction-finding performance during engineering implementation，a high-precision direction finding method suitable for arbitrary structured arrays is proposed.This method introduces a linear transformation matrix to directly extract high-dimensional angular information from measured amplitude-phase relationships，thereby improving the impact of various error factors in engineering implementation.Both simulation and experimental results demonstrate that the proposed method has no restrictions on the instalation positions of array elements， achieves high direction-finding accuracy，has relatively simple computations，and exhibits significant engineering application value.
