Abstract: In the future commercial and military communication systems, anti-jamming remains a critical issue. Existing homogeneous or heterogeneous arrays with a limited degrees of freedom (DoF) and high consumption are unable to meet the requirements of communication in rapidly changing and intense jamming environments. To address these challenges, we propose a reconfigurable heterogeneous array (RHA) architecture based on dynamic metasurface antenna (DMA), which will increase the DoF and further improve anti-jamming capabilities. We propose a two-step anti-jamming scheme based on RHA, where the multipaths are estimated by an atomic norm minimization (ANM) based scheme, and then the received signal-to-interference-plus-noise ratio (SINR) is maximized by jointly designing the phase shift of each DMA element and the weights of the array elements. To solve the challenging non-convex discrete fractional problem along with the estimation error in the direction of arrival (DoA) and channel state information (CSI), we propose a robust alternative algorithm based on the S-procedure to solve the lower-bound SINR maximization problem. Simulation results demonstrate that the proposed RHA architecture and corresponding schemes have superior performance in terms of jamming immunity and robustness.
