摘　　要：基于离散混沌系统 ,为克服有限精度效应 ,采用了m序列对logistic映射进行异或扰动的方法来构造混沌跳频序列 ,并分别采用FPGA进行数字仿真 ,研究结果表明 :其仿真得到的混沌跳频序列具有较长的周期、符合理论值的相关性和较小的平衡性 ,研究结果表明 :该方法是可行的 。In order to overcome the finite precision effect, the logistic map with xor perturbation of the m sequence is presented in this paper to generate chaotic frequency hopping sequence using the discrete chaotic system. The simulated numerically result with FPGA indicates that the sequence has long periods, small balance demands, and its correlation property fits the theory, which shows the method is feasible and is available for generating the short wave frequency hopping sequence.
