Abstract
A method for estimating object angle with high-angle analysis using a large-scale MIMO array antenna, wherein the array antenna receives the input signal matrix which is the transmission or reflection signal of at least one object. The method includes: step S1: inputting the input signal matrix to a first calculation model to obtain a target object amount and a rough object angle with respect to the location thereof; step S2: inputting the object amount and the input signal matrix to a second calculation model for singular value decomposition to obtain a noise matrix; step S3: obtaining an iteration angle range from the rough angle in S1; step S4: inputting the plurality of pursuit matrices corresponding to the iteration angle range and the noise matrix to a third calculation model for angle range iteration, thereby acquiring an accurate object angle.
