Backscatter, in its most basic definition, refers to the phenomenon where waves or radiation are scattered backwards in the direction of the source after interacting with an object or medium. This diffusion occurs when waves encounter obstacles, particles, or boundaries that reflect or disperse the waves toward their origin.
Backscatter is commonly observed in various fields such as radar, medical imaging, underwater acoustics and remote sensing, where it plays a crucial role in the detection, imaging and analysis of objects and environments based on reflected or scattered signals.
Backscatter is defined as the reflection or scattering of waves or radiation back to the source after interaction with a material or medium. This phenomenon is characterized by the redirection of waves or radiation in the direction opposite to the propagation of the incident wave.
The intensity and characteristics of backscattered signals provide valuable information about the properties, composition and spatial distribution of the objects or media that caused the scattering. Engineers and scientists use backscatter in a variety of applications for purposes ranging from environmental monitoring to medical diagnostics and surveillance.
Backscatter explained involves understanding the mechanism by which waves or radiation are redirected back to their source. When waves encounter objects or boundaries comparable in size to their wavelength, scattering occurs.
Backscatter refers specifically to the scattering of waves or radiation toward the source rather than in other directions. The analysis of backscattered signals allows the detection and characterization of objects based on their reflective properties and the nature of the interaction with the incident waves. This principle is fundamental in technologies like radar, where backscatter is used to detect and track targets, and in medical imaging, where backscattered radiation provides insight into tissue density and composition
