摘　　要：该文通过对实测跳频通信和捷变频雷达跳频码的混沌动力学特征量,如奇异吸引子、最大李亚普诺夫指数、关联维数的分析和计算,说明了跳频通信和捷变频雷达跳频码确实具有混沌特性,是一种混沌现象。这对从理论上认识跳频通信和捷变频雷达跳频码的本质,具有重要的理论意义。This paper illustrates that Hopping Frequency (HF) communication and frequency agile radar have chaotic peculiarities, and are chaotic phenomena, with computing singular attractor and their correlative dimensions and Lyapunov exponents from simulation. It has important significance to recognizing HF communication and frequency agile radar on theory and essence.
