%X In this paper, a complex Linear FM (LFM) signal model is given, and a transform called Cyclic-Correlation Transform (CCT) is introduced. Then, a new method combining CCT with ?clean? technique for multipath LFM signal detection and parameter estimation is presented. Multipath LFM signal parameters, time delays and attenuation factors are estimated precisely with this method, and the correlated cross-item can be avoided effectively. The relevant conclusions are got and verified by the computer simulation.
