A new method to obtain the real height profile of ionospheric electron density is described, which is called 'approximation with network'. Also it has been demonstrated how to solve the group path integral equation with Back Propagation(BP) neural network, and given the computation results with this method for a parabolic model.Simulation results show that the proposed method is effective. 展开更多
