Abstract

본 논문에서는 지상의 추적 장비들이 무선망으로 연결되어 협력하는 전술형 모노펄스(Monopulse) MIMO 레이더의 성능 향상 기법을 연구하였다. 우선, 기존의 모노펄스 MIMO 레이더에 <TEX>${\alpha}{\beta}$</TEX> 필터를 적용하여 각도 다이버시티(Angular Diversity)를 충분히 얻지 못하는 환경에서의 위치추적 성능을 크게 향상시키는 방법을 제안하였다. 또한 필터링 기법과 연계하여 무선망을 이용하는 지상 추적 장비간 피드백(Feedback)을 줄일 수 있는 기법을 제안하였다. In this paper, we proposed an enhanced monopulse MIMO radar system for the tactical scenario where the ground receivers are connected wireless backhaul and closely spaced. By applying the <TEX>${\alpha}{\beta}$</TEX> filter to the conventional monopulse MIMO radar, we show that the localization performance can be improved significantly. We also propose an efficient localization algorithm for a system with lower rate feedback. Using numerical simulations, we demonstrate that the proposed scheme can improve the localization performance while reducing the feedback over conventional scheme.
