摘要: This paper analyses the existing methods for linear frequency modulated (LFM) signal parameters estimation methods. A new fast algorithm named as local iterative searching dechirp which combined segmented correlation method, interpolation and extrapolation method golden section together to get accurate of LFM parameters. After that, validity this has been simulated when is not exist at beginning or ending received signal.
