What type of reflector is associated with the phenomenon of double bounce?

The type of reflector associated with the phenomenon of double bounce is known as a corner reflector. This type of reflector typically consists of three mutually perpendicular surfaces that form a corner, such as the inside corner of a cube. When radar waves hit the corner reflector, they bounce off the surfaces in two separate reflections before returning to the radar source. This process is what defines the double bounce effect, providing strong radar returns that can be advantageous for detecting and monitoring objects, particularly in urban environments where building geometries create numerous corner reflectors.

The distinct nature of the corner reflector allows it to effectively redirect signals back towards their source, making it a crucial component in radar and remote sensing applications. This property is exploited in various fields, including geospatial intelligence, to enhance the visibility of targets in complex landscapes.
