초록

본 논문은 전투기 레이다의 표적 추적정확도(추적오차)를 분석하는 방법에 대한 연구이다. 레이다 측정 시 발생하는 측정오차, 탐지실패, radar cross section(RCS) 요동은 측정 품질을 열화시키며, 이는 추적정확도에 영향을 미치는 요인이 될 수 있다. 따라서 정확한 추적성능분석을 위해 이러한 레이다 측정 특성을 고려하는 것이 필요하다. 본 논문에서는 측정오차, 탐지확률, RCS 요동과 같은 레이다 특성을 복합적으로 활용하여 추적정확도를 분석하는 방법에 대해서 제안한다. 제안한 분석 방법을 활용한 실험을 통해 탐지확률과 RCS 요동에 의한 추적정확도 열화를 확인할 수 있었다.

This study analyzes the tracking accuracy(tracking errors) of fighter radar. Measurement error, detection failure, and radar cross section(RCS) fluctuation in radar measurements degrade the measurement quality and hence affect the tracking accuracy. Therefore, these radar measurement characteristics need to be considered when analyzing the tracking accuracy. In this paper, a method for analyzing the tracking accuracy is proposed; this method considers the detection error, detection probability, and RCS fluctuation. Results from experiments conducted with the proposed method show that the detection probability and RCS fluctuation affect tracking accuracy.
