Abstract
Provided is an improved beam control method of an array antenna based on frequency diversity. The method includes: signals from a transmitter are received by a receiving array which includes a first sub-array and a second sub-array, wherein the first sub-array includes M uniformly arranged array elements, the second sub-array includes N uniformly arranged array elements, M and N are coprime integers, and N≥0; a signal received by each array element in the receiving array is input into a constructed model, and a covariance matrix is output after processing the signal via the model; a virtual array is constructed at a receiver, wherein a virtual array element in the virtual array is a second-order statistic calculated according to the covariance matrix; and a frequency is randomly selected for each virtual array element from a frequency set of the virtual array, so as to form a beam pattern.
