Abstract In ultrasonic nondestructive evaluation and sonar imaging, scattering contributions by leaky waves on truncated objects can be important for enhancing the visibility of certain of the borders of the scatterer. A method of approximating the leaky wave contributions is reviewed together with recent experimental and computational tests for evaluating that method in situations where the scattering contributions are large. The tests include meridional ray contributions to the scattering by tilted solid cylinders and cylindrical shells and Rayleigh wave contributions for steel cubes in water.
