- Abstract:
- The paper studied a Deformation Ｒossler System，which is added a cycle power signal to the Ｒossler system． The Deformation Ｒossler System is proved to be a chaotic system by its Poincare mapping，the maximum Lyapunov exponent，and fractal analysis． By adopting Wolf method to calculate the Maximum Lyapunov exponent and its Usage for quantitatively judge states of the Ｒossler chaos detection system． The ruslut of the SIMULINK simulation proved that the minimum SNＲ of the Deformable Ｒossler system can be lower to － 57dB and immune to a certain power of gaussian white noise． With the simulation contract of the weak signal detection，it is showed that the threshold detection precision is higher in the Deformable Ｒossler chaotic system than those in Ｒossler and Duffing system．
