  • Infrared transparent radar antenna
    Patent number: 6150974
    Abstract: A dual mode missile seeker system utilizing an infrared transparent radar tenna is disclosed. The infrared transparent radar antenna is mounted in front of and on the same axis as the infrared detector within a missile dome. The radar antenna includes spaced apart patches of infrared transparent semiconductor material and a ground plane of the same material deposited on opposite sides of an infrared and microwave transparent dielectric substrate for transmitting and receiving microwave radiation and for shielding the infrared detector array mounted behind. A radome or separate lens redirects incoming infrared radiation so as to pass through the radar antenna and focus on the infrared detector array.
