单个脉冲载波频率的快速估计

小波变换中的小波系是把基本小波进行伸缩和时移得到的,根据这一原理,提出一种快速估计单个脉冲载波频率的算法。该算法通过把基准单个脉冲进行伸缩和时移处理来构建一个函数系,然后求解该函数系中和被测单个脉冲相关性最大的函数,由该函数相对基准脉冲的尺度因子估计出被测单个脉冲的载波频率。文中对该算法进行了仿真验证。

Fast Frequency Estimation of Single Pulse Carrier

Based on the principle of getting wavelet function through stretching and time-shifting wavelet base in wavelet transform,puts forward a method of the fast frequency estimation of the single pulse carrier.A function frame is constructed through stretching and time-shifting the base single pulse in this method,then works out the function in the function frame and the maxim relativity with measured single pulse,and the frequency of measured single pulse carrier is estimated from the scale factor of this function relative to basic pulse.At last,the arithmetic is emulated and validated.
