摘要
对基于Duffing振子的微弱特征信号检测中的相变量化测度进行了研究,提出一种新的相变指标———基于连续多分辨率q熵的相变量化测度,数值计算结果验证了该方法的有效性。
Phase transition quantitative measure of weak signal detection based on Duffing oscillator is analyzed and continuous multiresolutiong entropy is put forward as a new quantitative measure index of phase transition.The feasibility is explored via numerical calculation.
