Latest Patents

One of Xiaopeng Li's latest patents is titled "Direction of arrival estimation method and device based on steering vector matrix reconstruction." This invention relates to array signal processing and involves obtaining an array sampling covariance matrix from an array received signal. The method includes setting a target variable and limiting its feasible domain using two operators to establish a first constraint condition. It characterizes an estimation error based on the target variable and the covariance matrix, using this error as a second constraint condition. An initial optimization model is established based on a preset norm, leading to a multivariable optimization model that is solved to obtain an optimal result, ultimately analyzing the result to determine the direction of arrival (DoA) of the target incident signal.

Another notable patent is the "Method and device for constructing redundancy-removed coprime radar array based on one-bit quantization." This invention outlines a method for constructing a radar array that eliminates redundancy through one-bit quantization. It involves obtaining sub-array elements and determining a corresponding redundancy-removed coprime array using graph theory. The method processes target echo data and performs one-bit quantization to complete the array cavities, ensuring that radars are placed in non-empty array element positions.
