Abstract: Provided are a method and apparatus (700) for determining an angle and a distance of a target (104, 200), a radar (102, 800), and a storage medium. The method includes: a frequency diversity signal is transmitted to a target (104, 200), and a received signal reflected by the target (104, 200) is received; hole filling processing is performed based on the equivalent received signal vector, so as to determine a uniform received signal vector; an equivalent received signal equation is performed based on the uniform received signal vector, and an objective function and a constraint condition is established for solving an objective optimization problem of the equivalent received signal equation (S240); and the objective optimization problem is solved to obtain an objective solution matrix, and the angle and the distance of the target is determined based on the objective solution matrix (S250).

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.
