微弱周期脉冲信号的取样积分-混沌系统联合检测方法

为提高混沌系统检测微弱周期脉冲信号的能力，提出把取样积分与混沌系统相结合的检测方案。仿真结果表明在相同系统实验背景下，相结合的检测方案优于不加取样积分的检测方法；周期脉冲信号占空比变小，使检测到的最小脉冲幅度变大；输入噪声强度的降低可使检测系统临界相态简化。

The United Detecting Method of Sampling Integral and Chaotic System for the Weak Periodic Pulse Signals

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 system. The simulation results indicate that the united detecting scheme precedes the detecting method without sampling integral under the same experimental background. Because occupied 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.
