Proloid and uniform dielectric lens reflectors are used for radar cross section enhancement using lenses with the same dielectric constant throughout the lens. The front of the proloid is a prolate spheroid whose dimensions and focal length are a function of dielectric constant. The front of the uniform dielectric lens reflector is a hemisphere whose focal length is a function of dielectric constant. It provides a viewing angle of about 100 degrees at millimeter wave frequencies.
