Definition: In physics and signal processing, backscatters refer to signals that are reflected off a surface or object. These reflections can occur due to different media types (e.g., glass, plastic, metal), which may cause them to be distorted or blurred in the receiver. For example, if you were to transmit a sound wave through a vacuum chamber and receive it back, the signal would likely be distorted because of the reflection off the walls and surfaces. The backscattered signal would not be as clear
