A New Time-frequency Transform Algor ithm for Multi-LFM Signals Parameter Estimation

摘要：

In this paper,a new time-frequency transform (NTFT) to estimate multi-component linear frequency modulated (multi-LFM) signal parameters is proposed.The NTFT is a linear transform and has a more simple form while compared to the conventional fractional Fourier transform (FRFT).The discrete NTFT with fast Fourier transform (FFT) algorithm offers a computationally disadvantage for LFM signal detection and parameters estimation.By utilizing NTFT with CLEAN technique,all the Multi-LFM signals components can be estimated seriatimly.Finally,computer simulations are provided to illustrate the good performances of the proposed algorithm.
