摘要

PROBLEM TO BE SOLVED: To provide a method for estimating a two-dimensional arrival direction in a relatively disjoint area array based on processing of a tensor signal of a structured virtual domain. SOLUTION: A step of constructing a mutually elementary area array, a step of tensor modeling a received signal of the mutually elementary area array, and a virtual domain of the mutually elementary area array based on the conversion of the mutual correlation statistics of the tensor signals. A step to derive a quadratic equivalent signal, a step to build a three-dimensional tensor signal of a virtual domain of an area array that is mutually elementary, and a step to build a tensor of a five-dimensional virtual domain based on a virtual domain tensor dimension extension strategy. , A step of forming a tensor of a structured virtual domain containing three-dimensional spatial information, and a step of acquiring a two-dimensional arrival direction estimation by tensor CANDECOMP / PARACFAC decomposition of the structured virtual domain.
