Abstract
The embodiments of the present disclosure 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 the direction-of-arrival approximation degree includes: respectively obtaining receiving vectors of a first target and a second target according to a processing result of a multi-channel echo signal, 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 using the method for determining the direction-of-arrival approximation degree, the real-time performance of multi-channel echo signal processing can be improved.
