Junxian Li, Sun Yuan-sheng, Yan Liu · Journal of Projectiles.Rockets.Missiles and Guidance · 2005
The paper advanced a novel Modified Discrete Chirp-Fourier Transform(MDCFT) to overcome the restriction,this new transform can make the signal energy concentrate in the transform domain to estimate the parameters.As the result,the good performance parameters estimation can be obtained.The comparison shows that the new algorithm is more practical and effective.
