Abstract

The accuracy of instantaneous passive emitter localization varies with sensing platforms and measurable parameters. Appropriate combination of instantaneous measurable parameters have more accurate localization performance than a single parameter based localization in general. Emitter localization is preferred to use a small number of receivers as possible for the efficiency of strategic management in the field of modern electronic warfare support. For this reason, we compare CRLB (Cramer-Rao lower bound) of two moving platform with various measurable parameters to search a appropriate choice of parameters for the better localization performance through the x-y axis CEP (circular error probable) derived form CLRB. In addition, we present the relation of the localization performance and accuracy of measurable parameters.

전자전 환경에서 위협 신호원의 순시 위치추정 성능은 위협과 다수의 수신기들의 기하학적 배치 및 측정 가능한 정보에 따라 가변되며, 상황에 맞는 복합적 정보의 선택 및 활용은 단일 제원을 이용한 경우보다 높은 위치추정 정확도를 가지는 것으로 알려져 있다. 현대의 전자전 지원(electronic warfare support) 분야에서는 전략적 운용의 효율성을 위해 적은 수의 수신기를 이용하여 원거리 위협의 정밀한 위치추정을 지향한다. 본 논문에서는 제한된 환경의 2개의 이동하는 수신기를 이용하여 고정 위협의 위치추정을 위해 측정 가능한 정보별 이론적 위치추정 성능을 도출 및 분석하고, 이를 기반으로 위치추정에 적합한 정보조합을 제시한다. 또한, 정보들의 변화에 따른 위치추정 성능을 분석 및 제시한다.
