Latest Patents
Zhou's latest patents include a two-dimensional direction-of-arrival estimation method for coprime surface arrays based on virtual domain tensor filling. This invention addresses the challenges of losing multi-dimensional signal structural information and the underutilization of virtual domain statistics in existing methods. The process involves constructing a coprime surface array, modeling a tensor of the received signal, and deriving a virtual domain tensor to achieve accurate direction-of-arrival estimation.
Another notable patent is the method for estimating the direction of arrival of an L-type coprime array based on coupled tensor decomposition. This method constructs an L-type coprime array with separated sub-arrays and models the received signal to derive a fourth-order covariance tensor. By utilizing the spatial correlation properties of the virtual domain tensor statistics, this invention enables high-precision two-dimensional direction-of-arrival estimation, which is essential for target positioning.
