Abstract In this paper, a new transform called Radon-Gabor transform(RGT) is proposed firstly, then the basic theory is introduced for Linear Frequency-Modulated (LFM) signal detection and parameter estimation using Radon-Gabor transform. Moreover, a new method combining Radon-Gabor transform with "clean" technique for multicomponent LFM signal detection and parameter estimation is presented. The computer simulation results show its effectiveness.
