Acoustic scattering of spherical directional waves by smooth and statistically rough solid elastic cylinders
Realistic sonars radiate spherically spreading waves and have directivity. Therefore, they insonify a target over a finite number of Fresnel zones and span a continuum of oblique incident angles, even when the center of the beam is at normal incidence. These effects strongly influence both the …
