backscattering
Waves bouncing backward
Backscattering is the reflection of waves, particles, or signals back toward their source.
In physics, radiation or particles strike a surface and scatter in the reverse direction.
Airport security scanners use X-ray backscattering to create images of objects beneath clothing.
In networking, backscatter refers to misdirected automated responses from spam or cyberattacks: The server was flooded with backscatter from spoofed emails.
