A technique for calculating an estimate of the lower ionospheric electron density profile from a knowledge of the VLF radio wave reflection coefficients is studied. The conditions of success of this technique are discussed in detail. Numerical simulation of this method has been carried out on the basis of a full wave calculation. It was confirmed that the deduced profile converged well to the specified profile after only a few iterations. Some numerical results are presented.
