Based on the wide-angle parabolic equation method, propagation characteristics of low-frequency radio wave in transition regions over irregular terrain are analyzed. The formula of the direction factor is deduced with certain assumptions. Electric field distributions within 60 km height of three path models are simulated, and the propagation characteristics are compared with those on the ground. By the proposed approach calculation schemes of the electric field both on the ground and in transition regions can be unified with high accuracy, which is important for solutions of the sky-wave propagation problems in a complex earth-ionosphere waveguide.
