根据国产移频轨道信号的特点,提出利用小波分析中多分辨率理论的检测方法来检测轨道信号瞬时值,基于Matlab软件平台对轨道信号的基带调制频率进行检测并对其误差进行测量。仿真结果表明,该方法能有效地降低移频轨道信号参数的测量误差,并具有很好的稳定性。

Based on the characteristics of domestic frequency shift key track signal, a detection method for instantaneous spectrum of it by using wavelet-multiresolution theory is presented in this paper. The baseband frequency and its error are measured on the basis of Matlab, and the simulation results show that this method can reduce the measurement error effectively and keep good stability.
