Abstract: In this letter, a machine learning-based algorithm, K-nearest neighbor, is employed to predict the actual patterns of the linear arrays with arbitrary positions and varied element numbers.

Abstract: This article proposes a novel calibration method for linear array antennas based on the scattering signals of a standard metal cylinder. The method sequentially activates each element of the ...
