本段代码用于检测在雷达中的SMSP干扰，为后续的干扰抑制提供先验信息(This Code is used to detect SMSP jamming)

说明：  针对Hénon map,找出其稳定点，. 以及在参数确定的情况下绘画出其分岔图，计算李雅普诺夫指数，最后做出时域图 (For Hénon map,1) Find the fixed points of periods one and two for the Hénon map. 2) Investigate the bifurcation diagrams for the Hénon map by plotting the x_n values as a function of α for β = 0.4. 3) Write a Matlab or Maple program to compute the Lyapunov exponents of the Hénon map where α=1.2 and β = 0.4. 4) Use the OGY algorithm to stabilize a point of period one in the Hénon map where α=1.2 and β = 0.4.)
