The reflectivity of the radar in an area is depending on the number, and size of deflectors.
The reflectivity of a material is the capability of the fabric to mirror the power incident on its surface. The reflectance of cloth is decided whilst light and sun radiation is incident on the floor of the fabric. This value can be used to describe the character of a surface in terms of the surface finish.
Reflectivity is the assets of the boundary among specific kinds of media even as reflectance is the assets of the boundary of between two specific times or samples of those media. For most opaque constructing materials of measurable thickness, reflectance values are essentially the same reflectivity values.
