Abstract In order to improve the ability of chaotic system detecting weak periodic pulse signals, this paper proposes the detecting scheme uniting sampling integral with chaotic sys-tem. The simulation results indicate that the united detecting scheme precedes the detecting method without sampling integral under the same experimental background. Because occu-pied space ratio of the periodic pulse signals diminishes, the detected minimum amplitude increases. The intension decrease of input noise can simplify the critical phase state of detecting system.
