主要研究了两种高动态扩频信号快速捕获的方法,即基于FFT 的频域(载波) 并行捕获法和基于FFT 的时域(伪码)
并行捕获法,并使用MATLAB 进行了仿真和比较。仿真结果表明:基于FFT 的频域并行捕获可捕获较大的频偏并跟踪一定
的频率变化率,可用于卫星变轨等高动态、高加速度等飞行过程。而基于FFT 的时域并行捕获可快速捕获码相位,用于在轨飞行的飞行器,可根据轨道参数提前预报其多普勒频偏,但同时需要精密测距的飞行过程。-Research on the quick acquisition

频谱分析仪是信号处理研究领域必不可少的工具。现有的基于快速傅利叶变换的频
谱分析仪能对线性的平稳的信号进行有效分析,但难以分析出非线性非平稳信号的瞬时频率
能量变化情况。针对此问题,本文设计了基于希尔伯特黄变换的频谱分析仪,能够对非平稳
信号进行有效分析。所设计系统以DE2-FPGA开发板为硬件平台,结合了NiosII的软核处
理器加以实现,可对采集的外部信号进行希尔伯特黄变换,得到信号的时间-频率-能量三维
谱,并可在VGA上实时显示出来。系统测试结果表明,所设计频谱分析仪
