Abstract Based on the finite difference method, the authors established the forward model for the ground-penetrating radar electromagnetic waves propagation in the river, simulated the typical conditions of different underwater formations, and obtained the corresponding 2D image. Through a comparison with the actual detecting reflected image of the river and an analysis of the simulation image and the interpretation of the actual radar detection image, the feasibility and rationality of the ground-penetrating radar method in detecting the river course were studied.
