Document Type and Number:
WIPO Patent Application WO/2023/056991
Kind Code:
A2
Abstract:
The embodiments of the present application relate to the technical field of signal processing. Disclosed are a MIMO sensor, a method for determining a direction-of-arrival approximation degree, and a target information matching method. The method for determining a direction-of-arrival approximation degree comprises: respectively obtaining receiving vectors of a first target and a second target according to processing results of multi-channel echo signals; calculating a correlation coefficient between the receiving vectors of the first target and the second target; and determining a direction-of-arrival approximation degree between the first target and the second target according to the correlation coefficient. By means of the method for determining a direction-of-arrival approximation degree, the real-time performance of multi-channel echo signal processing can be improved.
