Antenna/optics system and method

摘要

A missile includes a radar system that has a radome through which a main antenna sends and receives signals. The radome includes a radome body and a radome tip include different transmissive materials, with for example the radome body primarily made of a lossy optically nontransparent material, and the radome tip primarily made of a lossless (permittivity with low imaginary part) glass material that may also be optically transparent. A laser may be used in conjunction with the radome to send and receive encoded signals. The laser may be located behind (aft of) the main antenna, and one or more optical fibers may extend into and/or along the radome to guide laser signals to the radome tip. The laser may be used to emit encoded signals so as to allow multiple radar systems operating in the same area at the same time to discriminate between different targets.

1. A missile radar system comprising:
a main antenna; and a radome enclosing the main antenna; wherein the radome includes a radome body and a radome wedge; wherein the radome body has a wide end and a narrow end, with the main antenna at the wide end, and the radome wedge at the narrow end; wherein the radome wedge and the radome body include different materials that are substantially transparent to radar signals emitted by the main antenna; and wherein the radome wedge and the radome body are formed as a single unitary piece of material.
