  title={Parameter Estimation of LFM Signals Using FrFT Interpolation},
  author={Yu Wen-xian},
The resolution of fractional fourier domain is determined by time-bandwidth product of signal,its finity reduces the accuracy of parameter estimation for linear frequency modulated(LFM) signals.For solving this problem,a novel approach using FrFT (fractional fourier transform) interpolation is proposed.The FrFT function of FrF domain is obtained with the factors analyzed which cause the errors.Using FrFT interpolation by the function,the approach breaks through the resolution of fractional… CONTINUE READING
