摘要
提出了一种精确估计线性扫描干扰扫描速率的方法,利用短时傅立叶变换分析扫描干扰信号,得到其时频分布,再利用其变换结果,实现扫描速率的估计。仿真计算表明,该方法复杂度低,估计精度较高。
The article shows a method that accurately estimates the frequency sweeping rate of linear chirp signal,utilizes STFT to analyze the linear chirp signal,and receives the time-frequency distribution;then makes use of the transferred result to implement the estimation of frequency sweeping rate.The simulation and computation indicate that the method is with low complexity and in high estimation precision.
