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.

Systems and methods for improving vehicle survivability. In some embodiments, threat information relating to at least one potential threat against at least one vehicle during a mission may be accessed. The threat information may comprise threat location information indicative of at least one likely location for the at least one potential threat and at least one model associated with the at least one potential threat. Prior to commencing the mission, the threat information may be used to assign a numerical measure to each potential action of a plurality of potential actions for the at least one vehicle based at least in part on at least one measure of the at least one vehicle resulting from executing the potential action. The plurality of potential actions may be compared based at least in part on the respective numerical measures assigned to the plurality of potential actions.

The method of claim 2, wherein the numerical measure assigned to the at least one potential action is a weighted sum of the first and second measures of signature exposure. 4. The method of claim 2, wherein the first signature exposure model is an infrared (IR) signature exposure model, and wherein the second signature exposure model is a radar (RF) signature exposure model. 5. The method of claim 1, wherein the one or more actions comprise a sequence of actions to be executed by the at least one vehicle in order, the sequence of actions being selected from the plurality of potential actions prior to commencing the mission. 6. The method of claim 5, wherein the sequence of actions is selected to reduce an aggregate numerical measure determined based on the respective numerical measures assigned to the actions in the sequence of actions. 7. The method of claim 1, wherein the threat location information comprises a probability distribution over possible locations for the at least one potential threat. 8. A system for improving vehicle survivability, the system comprising at least one processor programmed to: access threat information relating to at least one potential threat against at least one vehicle during a mission, the threat information comprising threat location information indicative of at least one likely location for the at least one potential threat, the threat information further comprising at least one model associated with the at least one potential threat;prior to commencing the mission, use the threat information to assign a numerical measure to each potential action of a plurality of potential actions for the at least one vehicle, the numerical measure being based at least in part on at least one measure of the at least one vehicle resulting from executing the potential action, wherein the at least one measure is determined based at least in part on the at least one likely location of the at least one potential threat and the at least one model associated with the at least one potential threat;compare the plurality of potential actions based at least in part on the respective numerical measures assigned to the plurality of potential actions, thereby generating a comparison result; andselect one or more actions to be executed by the at least one vehicle, the one or more actions being selected from the plurality of potential actions based at least in part on the comparison result. 9.
