How Is the Scattering Angle Measured in Lidar VSF Applications?

[vani]

How is the angle determined in volume scattering function in water for a lidar application?

The volume scattering function(VSF) for water is given by,
VSF(teta) = A(lambda, S)*(1-cos power 2of teta(1-delta)/(1+delta))
where teta is the direction of scatterred radiation.
A is amplitude
lambda is wavelength
S is salinity
delta is depolarization ratio.

How is scatterred direction angle taken for the measurement of VSF i.e. in what range of angles(0, 90,...etc)?

The angle for the measurement of VSF is usually taken in the range of 0° to 180°. The angle is determined by the orientation of the lidar beam relative to the surface of the water, as well as the range of angles that needs to be measured.

The angle for the measurement of VSF in water for a lidar application is typically taken in a range of 0 to 180 degrees. This range covers the full hemisphere of possible scattering directions. However, the specific angle range may vary depending on the specific lidar instrument and its capabilities. Some lidar systems may be able to measure scattering angles beyond 180 degrees, while others may have a limited range. Additionally, the angle range may also depend on the specific research or application being conducted. For example, some studies may only be interested in forward scattering (0-90 degrees), while others may focus on backscattering (90-180 degrees). Ultimately, the angle range for VSF measurements in water will depend on the specific parameters and goals of the experiment or application.
