초록

본 논문에서는 비행 중인 플랫폼에 탑재된 소형 AESA 레이다의 추적 성능 향상을 위한 빔 조향 안정화 알고리즘을 제안하였다. 동체 기동으로 인한 외란을 보상하기 위해, 자이로스코프로 계측된 3축 자이로 각속도를 안테나 좌표계에서 사용하는 방위각, 고각으로 변환하여 조향각에 반영하였다. 제안된 알고리즘은 MATALAB Simulink를 이용한 시뮬레이션을 통해 검증하였다.

Abstract

In this paper, we propose a beam steering stabilization algorithm designed to improve the tracking performance of a small AESA radar on a flight platform. To compensate for disturbances of body motion, the 3-axis angular rates measured by a gyroscope are transformed into azimuth and elevation steering angles used in the antenna coordinate system and then integrated into the steering commands. The proposed algorithm was verified through simulation by using MATALAB Simulink.
