연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison, Kafe, Webinar 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

1. A system for locating a target and guiding a vehicle based on a position of said target comprising:first means for tracking a vehicle based on time-of-arrival information associated with energy transmitted from said vehicle and providing vehicle position information in response thereto; second means for steering said vehicle based on said vehicle position information; and third means for employing said first means to locate a target based on time-of-arrival information associated with energy transmitted from said target and providing target location information in response thereto, said second means further including means for steering said vehicle based on said target location information and said vehicle position information. 2. The system of claim 1 wherein said vehicle is an intercepting missile.3. The system of claim 1 wherein said third means includes three or more receivers equipped to determine said target location information and said vehicle position information based on energy transmitted from said target and said energy transmitted from said vehicle, respectively.4. The system of claim 3 wherein said three or more receivers include means for performing trilateration based on said energy transmitted from said target and transmitted from said vehicle.5. The system of claim 4 wherein said target is a ground-based target, and wherein said three or more receivers are positioned on three or more aircraft and/or spacecraft.6. The system of claim 5 wherein said target is an aerial vehicle.7. The system of claim 6 wherein said aerial vehicle is an unmanned aerial vehicle.8. The system of claim 7 wherein said energy transmitted from said target includes television signals.9. The system of claim 8 further including fourth means for dispatching said vehicle in response to detection of said target by said third means.10. The system of claim 9 wherein said fourth means includes a portable missile launcher in communication with a controller associated with a master receiver included in said three or more receivers.11. The system of claim 10 wherein third means includes means for providing time-of-arrival information associated with said energy transmitted from said target and said energy transmitted from said missile from said three or more receivers to said controller on said master receiver.12. The system of claim 11 wherein said controller includes a mechanism for computing said target location information and said vehicle position information based on said time-of-arrival information.13. The system of claim 12 wherein said missile includes a radiator and wherein said energy transmitted from said missile is electromagnetic energy having a predetermined waveform.14. The system of claim 13 wherein said first means includes an algorithm running on said controller for computing said missile position based on time-of-arrival information associated with said energy transmitted from said missile; detected by said three or more receivers; and provided to said controller in communication with said master receiver.15. The system of claim 14 wherein said second means includes a guidance algorithm running on said controller, said guidance algorithm generating steering commands and forwarding said commands to said missile to command a missile steering system included on said missile.16. A system for locating a target comprising:first means for receiving television signals from said target and providing timing information in response thereto and second means for locating said target based on said timing information. 17. The system of claim 16 wherein said target is a moving vehicle.18. The system of claim 17 wherein said moving vehicle is an unmanned aerial vehicle.19. The system of claim 18 further including third means for guiding a missile toward said aerial vehicle based on a location of said vehicle determined via said second means and based on positions of said missile as determined via said second means via energy transmitted from said missile.20. The system of claim 19 wherein said second means includes one or more receivers arranged to perform trilateration on said television signals and said energy transmitted from said missile to determine said location of said aerial vehicle and said positions of said missile.21. A method for locating a target and guiding a vehicle based on a position of said target including the steps of:tracking a vehicle based on time-of-arrival information associated with energy transmitted from said vehicle and providing vehicle position information in response thereto; steering said vehicle based on said vehicle position information; and locating a target based on time-of-arrival information associated with energy transmitted from said target and providing target location information in response thereto, further including the step of steering said vehicle based on said target location information and said vehicle position information.
