Model-based Synthesis Method of Multiple Patterns Linear Arrays with the Minimum Number of Antenna Elements: A State Space Approach

Abstract

Abstract-In this paper, we propose a synthesis method for synthesizing the reconfigurable multiple patterns with the minimum number of antenna elements based on the state space model. The proposed method is to obtain the common element locations for the multiple patterns using fewer antenna elements within desired performance bounds. The proposed approach introduces the statespace method to represent the multiple patterns and then uses the multiple pattern data to construct a combined Hankel matrix which is used to estimate the model parameters from which the number of elements and the common element locations can be extracted. Numerical results show the effectiveness of the proposed methods.Index Terms-Multiple patterns, state space model, antenna pattern synthesis, non-uniformly spaced arrays
