| 摘 要： | 混沌信号由于其特有的性质，在雷达中具有广阔的应有前景。该文利用基于Ｗｉｎｅｎ电桥和负阻转换器电路，产生的双卷吸引子混沌信号，获得了相应的混沌二相码序列雷达波形。借助于集成电路模拟程序模拟结果，讨论了该二相序列的二值均衡性和游和分布与电路参数的关系。

| Abstract: | As a special signal,chaotic signals have wide prospect in the field of radar.A waveform of chaotic binary sequence is produced by means of the double scroll attractor based on Wien bridge with a negative impedance converter in this paper. As the simulating results of simulation program with intergrated circuit emphasis(SPICE),the equilibrium of two values and the distribution of the run lengths is discussed by means of the rusults of SPICE.At last the ambiguity function of the waveform is analysed.The results show that it has an approximate thumbtack shape,and has good range and velocity resolution,and good characteristics of electronic counter countermeasures (ECCM). |
