  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.
