RadarBeacons are navigational equipment that helps the navigators avoid dangerous rocks, such as heavy fog, nighttime, etc. when ships operate, or when visibility is bad. The existing antenna was researching the development of the advanced radar eacon (Enhanced Radar Beacon) for improving the development of the next generation racon with the AIS (Automatic Identification System) function.

해상에서 안개 등 시계불량 시 항행 위험을 알려주는 중요한 기능을 하는 레이다 비콘은 세계에서 5 ~ 6 종류를 사용하나, 발사부호 및 발사주기의 조정이 어려운 실정이며, 레이다비콘의 정상적 동작 여부를 확인하기 위해서는 선박의 레이다를 작동시켜 그 동작 여부를 확인하는 방법을 사용하는 등 유지관리가 어려운 실정이다. 이러한 불편을 해소하기 위해 본 연구에서는 전 세계에 상용되는 레이콘을 하나의 기기에서 감시 제어 및 조정기능을 할 수 있는 장치를 전 세계에서 처음으로 개발하였다.

This paper presents a tracking filter of radar beacon system (RBS) for automatic takeoff and landing of an unmanned aerial vehicle. The proposed tracking filter is designed as the decoupled tracking filter to reduce the computational burden. Also, an adaptive estimation method of the measurement error covariance is proposed to provide an improved tracking performance compared to the conventional decoupled tracking filter whenever the accuracy of RBS observations is degraded. 100 times Monte Carlo runs performed to analyze the performance of the proposed tracking filter in case of normal operation and degraded operations, respectively. The simulation results show that the proposed tracking filter provides the improved tracking accuracy in comparison with the conventional decoupled tracking filter.

Range resolution is the ability to distinguish different targets placed in same angular direction but at different distances from the radar. Normally, Range resolution requirement is defined as the width of transmitting pulse. The width of transmitting pulse does not mean the ability to distinguish two different targets. Range resolution performance to detect and track targets separately depends on the signal processing and tracking algorithm not only the width of transmitting pulse. This paper analyzes the processing steps in algorithms to affect the range resolution performance and verifies the results by roof-lab ground test using beacon signal. As a result, to track targets with the same angular position separately, it is desirable to have larger range difference than plot-track association test gate.
