针对噪声雷达信号源产生难的问题，提出一种基于函数驱动的混沌雷达波形设计方法。通过分析函数xn ＝ p（θTzn ）和耦合不可逆变换的非线性映射之间的联系，理论上证明此类系统能产生不可预测的动力行为。据此原理可以构造出混沌系统，能产生真随机的混沌信号。仿真结果表明，该混沌信号及其频率调制信号都具有类δ的自相关函数，功率谱平坦，十分适合于宽带高分辨雷达的应用。

A function?driven method was proposed of chaotic radar waveform design to solve the difficulty of noise radar signal source generation. The connections between functions of xn = p θTzn and nonlinear maps coupled to non?invertible transformations were investigated. It was proved theoretically that these systems could produce unpredictable dynamics. According to this principle we can construct chaotic system which can produce true stochastic chaotic signal. Simulation result suggested that this chaotic signal and frequency?modulated signal had?like autocorrelation function and flat power spectrum it is very suitable for wide band high resolution radar application.
