| 摘 要： | 为了考察M序列BPSK引信信号的特征,对M序列BPSK引信信号进行了仿真建模与分析;首先分析了M序列BPSK信号的数学模型以及M序列的数学模型,给出了一种M序列的计算机产生程序;然后应用SIKULINK做出了实际应用中的M序列产生器的仿真模型,并给出了仿真结果,再按照M序列BPSK脉冲信号的产生原理,使用SIMULINK仿真模型仿真得到引信中经常使用的127位M序列BPSK脉冲信号;最后,利用Matlab软件的作图功能,从自相关函数、频谱函数和模糊函数三个方面对M波形的性能进行了仿真分析.结果显示M序列BPSK信号有良好的扩谱效果,并揭示了M序列的阶数与信号各项性能的关系.

| Abstract: | In order to study the character of M sequence BPSK signal,the paper carries out simulation modeling and analysis on it.Firstly,the mathematical model of M sequence BPSK signal and M sequence is analyzed,and a program of M sequence generator is given.Then,SIMULINK model of M sequence generator used in engineering is constructed and the simulation result is given.And then making use of the M sequence generator,the paper simulates 128 bits M sequence BPSK pulse signal by SIMULINK which is often used in fuse based on the principle of M sequence BPSK fuze signal generator.At last,making use of the plotting function of MATLAB,the paper carries out simulation analysis from three aspects: auto-correlation function,spectrum and fuzzy function.The results show that M sequence has excellent widen-band effect and reveal the relationship between rank of M sequence and signal performance. |
