The eigensystem realization algorithm (ERA) was used to identify the modal parameters of a membrane antenna system. The configuration of the membrane system and then the basic theory of ERA were introduced. The modal parameters of a flexible beam and the membrane antenna system were identified by the ERA. The simulation results indicate that the ERA is effective to identify the lowerorder natural frequencies and modal shapes of the membrane antenna system.
