Scattering of Sound by a Rigid Movable Sphere

摘要: The echoes from a rigid, freely movable sphere, due to an incident train of plane waves, are computed, together with the associated rigid‐body motions sphere. These results compared those for immovable sphere and it is shown that they differ significantly only values ka below about 5. significance in relation previous work on sonar solid, elastic spheres water discussed. A particular case forced motion rigid where diminish zero at high frequencies, also investigated.
