摘要
根据小波分析理论,针对无源北斗导航定位系统初始校频问题,提出了一种基于小波分析的信号特征提取算法。仿真结果表明该方法比较简单而切实可行,能够有效地对信号进行趋势估计,从而精确算得频标准确度。
According to wavelet analysis theory, a signal picking up algorithm based on wavelet analysis is proposed to solve problem of passive CNS initial frequency calibration. The simulation result suggests that the approach is simple and practical, which can effectively estimate the signal trend and accurately calculate the frequency accuracy.
