摘要
以恒流式混沌微弱信号测量系统为基础,利用混沌系统进行微弱信号测量.依据混沌系统的参数敏感性,用计算机对系统进行数值仿真.根据仿真结果,对该系统的线性度、分辨率、可测范围等关键参数进行分析,得出系统的理想分辨率可以达到10-8,轨道距离与理想轨道距离的最大最小偏移量分别为0.0517和0.0032.
To discuss the theory of using chaotic system measure feeble signal with the constant current source, according to the parameters sensitivity, computer numerical simulation is carried out. In this paper we analyzied the pivotal parameter of linear complexity, resolution and measurement range. The computer numerical simulation shows that the ideal resolution can reach 10^-8 and the max and least deviation between actual orbit distant and ideal orbit distant are 0. 052 7 and 0. 003 2.
