Method for designing non-uniformly spaced linear array antenna and computer-readable storage medium for executing same

Abstract

This application relates to a method for designing a non-uniformly spaced linear array antenna. The method includes setting a cost function for spacing between a plurality of antennas comprised in a linear array and for weights for each of the antennas, with limits on side lobe level and bandwidth, and obtaining an initial best solution vector for the cost function under an initial environmental condition based on learning parameters. The method may further include updating the initial best solution vector through reinforcement learning in which a reward value is computed by comparing a sub best solution vector with each of a plurality of solution vectors for the cost function under a sub environmental condition based on the initial best solution vector. The method may further include determining the spacing between the plurality of antennas and the weights for each of the antennas based on the updated initial best solution vector.
