Forward scattering is the deflection of waves by small angles so that they continue to move in close to the same direction as before the scattering. It can occur with all types of waves, for instance light , ultraviolet radiation, X-rays as well as matter waves such as electrons , neutrons and even water waves .
The Back Scattering Alignment (BSA) coordinate system is often used in radar applications The Forward Scattering Alignment (FSA) coordinate system is primarily used in optical applications Backscattering properties of a target are wavelength dependent and can also be polarization dependent.
The general alternative coordinate system in electromagnetic scattering is the Back Scattering Alignment (BSA) which is primarily used in radar. Both coordinate systems contain essentially the same information and meaning, and thus a scattering matrix can be transformed from one to the other by use of the matrix,
Later, other varieties of the effect were found. For example, the transverse Kerker effect, with nearly complete simultaneous suppression of both forward and backward scattered fields (side-scattering patterns), [18] optomechanical Kerker effect, [19] in acoustic scattering, [20] and also found in plants.

The alternative coordinate system in electromagnetic scattering is the Forward Scattering Alignment (FSA) which is primarily used in optics. Both coordinate systems contain essentially the same information and meaning, and thus a scattering matrix can be transformed from one to the other by use of the matrix [1],
For example, in Rayleigh scattering, the intensity scattered at the forward and backward angles is greater than the intensity scattered sideways, so the forward differential scattering cross section is greater than the perpendicular differential cross section, and by adding all of the infinitesimal cross sections over the whole range of angles ...
This is one of the most robust interference phenomena that survives multiple scattering, and it is regarded as an aspect of a quantum mechanical phenomenon known as weak localization (Akkermans et al. 1986). In weak localization, interference of the direct and reverse paths leads to a net reduction of light transport in the forward direction.
- Backward scattering – occurring at an angular distance higher than 90° from the major source of light. In daylight conditions, the distant objects located in the antisolar direction are better visible, because the backward scattering doesn't reduce the visibility as strongly as forward scattering.
