Abstract

With the physical optics method, the laser backscattering property of a cone-shaped object is introduced in this paper. First, the far field scattering amplitude of a rough surface illuminated by a plane light wave is deduced with the Kirchhoff approximation. The stationary phase method is employed to deal with some complicated integral factor. Finally, analytical form of a laser scattering intensity is derived for a cone-shaped object. To verify this model, the far backscattering intensity distribution is calculated and analyzed with its conic angle and surface roughness. These results show that the far backscattering intensity of cone-shaped objects is related with conic angle, its surface roughness and light wavelength.
