| 摘 要： | 为研究电路参数对ＳＡＷ相关器输出信号的影响，建立了一种把ＳＡＷ相关器和包络检波器视为一体的数学模型，通过对ＳＡＷ相关器进行计算机模拟分析，给出了本地参考信号的格式、相关峰顶点检测方法、本地参考信号中心频率偏差和码元宽度误差的允许范围，并给出了相关峰的实验结果，与模拟计算机结果做了对比，在此基础上完成了扩频信号相关解调解扩电路的设计。

| Abstract: | In order to study the influence of circuit parameters on out put signals of the SAW correlator. this paper presents a mathematical model for.the SAW correlator and detector, and gives the results of analysis including the formats of reference signal, detecting methods of correlative peak, tolerance of frequency shift between input signal and reference signal and admitted variation of the code period. The results has been proved by experiments. Based on analysis a circuit of spread spectrum signal demodulation has been designed. |
