What does backscatter mean?
Backscatter is a term used to describe the scattering of particles or radiation back in the direction of their origin. This phenomenon is commonly observed in physics, particularly in the study of wave propagation and particle interactions. In engineering, backscatter is utilized in various applications, including radar technology, where it helps detect and track objects. The term is also used in computing to describe a type of radar echo. Understanding backscatter is essential in fields such as meteorology, physics, and engineering, as it provides valuable information about the properties of materials and the behavior of waves. By analyzing backscatter, researchers can gain insights into the characteristics of surfaces, atmospheres, and objects.

Etymology of backscatter
The term 'backscatter' originated from the combination of 'back' and 'scatter'. The word 'scatter' comes from the Old Norse 'skattr', meaning 'to scatter', and 'back' refers to the direction from which something comes. The term has been used in physics and engineering since the mid-20th century to describe the phenomenon of particles or radiation being scattered back in the direction of their origin.
Usage notes
In physics and engineering, backscatter is a common phenomenon; in computing, it refers specifically to a type of radar echo.
