%X To solve the problem of reconstructing profiles of layered media (RPLM), at first a new time-domain mathematical model for EM wave propagation it; lavered med(?)a is presented. Secondly, the problem for RPLM is reduced to a paramerer Men(?)tion one with distributed parameter system. Then a new effective method of RPLM is presented. The method is better than the reconstruction method using reflection coefficient or impluse response to inverse its potential function. A fast identification algorithm is obtained by making ase of the step-gradient layered inversion method. Finally, a digital simulation example shows the feasibility of the algorithm.
