System and method for providing a frequency selective radome

摘要

A system including a first dielectric layer comprising a solid material configured to form a first layer of a radome, and a second dielectric layer comprising a solid material configured to form a second layer of the radome. The first dielectric layer and the second dielectric layer are spaced apart to provide an inner gap configured as a third layer of the radome. The inner gap is exclusively filled with a gas. The radome is configured to provide for the radome to be frequency selective. A radome and method are also disclosed.

1. A system, comprising:
a first hemisphericallv shaped dielectric plate comprising a solid material configured to form a first layer of a radome, the first plate having a hemispherically shaped inner surface and a hemispherically shaped outer surface; a second hemispherically shaped dielectric plate comprising a solid material configured to form a second layer of the radome, the second plate having a hemispherically shaped inner surface and a hemispherically shaped outer surface; and a void corresponding to separation between the hemispherically shaped inner surface of the first plate and the hemispherically shaped inner surface of the second plate, the separation having a distance determined to reflect certain wavelength signals to reduce radar cross section and/or electromagnetic interference; wherein the void being configured as a third layer of the radome and is exclusively filled with a gas; and wherein the radome is configured to be frequency selective.
