摘 要：正An improved Forward-Backward TimeStepping （FBTS） method has been *** this method,the distribution of estimate electrical parameters in seeking region is expanded in terms of Fourier series,to get a new gradient by controlling the number of the series truncation.A very convenience edge-preserving regularization has been proposed.
