摘要
为获得高的分辨率，介绍了现代谱估计方法中的扩充Prony方法，并利用该方法和传统的FFT方法分别对正弦信号进行仿真计算。理论分析及仿真结果表明：扩充的Prony方法具有比传统的FFT方法高的谱估计精度。最后，将该方法用于弹道测速雷达的测量数据的处理，获得了较好的结果。
In order to get higher resolution, extending Prony method was introduced, and simulating data using FFT method and Prony method was given. The results show that the Prony method has higher resolution and accuracy than FFT. Finally, this method was used in estimating the Doppler frequency and the results are satisfactory.
