Abstract

There are TOA, TDOA and AOA method to estimate the position of the electromagnetic wave transmitter by using the multiple receivers at the fixed position. Among these methods, AOA method is suitable for the jammer localization system. Because TOA method can be adopted for the clocks of the transmitter and the receiver are synchronized each other, and TDOA method can be only adopted for a broad-band jamming signal. This paper, therefore, analyzes the characteristics of the AOA measurements and the sensitivity of the positioning performance according to the system design parameters. Based on the analyzed results, the jammer localization system to meet the desired performance is designed, and it has been checked that the positioning error for the jammer located at a distance of 10km is lower than 38m through the simulation results.

위치가 고정된 다수의 수신기를 이용하여 전파 송신기의 위치를 추정하는 기법으로 TOA, TDOA, AOA 기법이 있다. 이 중 TOA 기법은 송신기와 수신기의 시각이 동기 되었을 경우에만 적용할 수 있고, TDOA 기법은 광대역 신호에만 적용할 수 있으므로 재머의 위치를 추적하기 위해서는 AOA 기법을 적용하는 것이 적합하다. 따라서 본 논문에서는 AOA 측정치의 특성을 분석하고, 시스템 설계 파라미터에 따른 측위성능 민감도를 분석하였다. 분석한 결과를 토대로 하여 목표 성능을 만족시킬 수 있는 재머 위치추적시스템을 설계하였고, 모의실험을 통하여 10km거리의 재머에 대한 위치추적 오차가 38m보다 작게 나타나는 것을 확인하였다.
