Abstract

Recently, ships have begun using the Asterix CAT 240 format as a method for transmitting radar image data to other devices. However, the Asterix format has a flexible structure that can be defined by the user, and a format structure defined as unsuitable for ship radar operation may undesirably increase navigational equipment network traffic or reduce stability. Therefore, to reduce the traffic of the navigation network and enhance the stability, a method of defining the optimized Asterix CAT 240 format with an appropriate setting value according to the performance of the radar scanner and display device was studied.

최근 선박에서는 레이더의 영상데이터를 타 장치로 전송하기 위한 방법으로 Asterix CAT 240 포맷을 사용한다. 하지만 Asterix 포맷은 사용자에 의해 정의 가능한 유동적인 구조를 가지고 있어, 선박 레이더 운용에 적합하지 않게 정의된 포맷 구조는 항해 장비 네트워크 트래픽을 과도하게 증가시키거나 안정성을 감소시킬 수 있다. 따라서 항해 네트워크의 트래픽을 감소시키고 안정성을 증가시키기 위하여, 레이더 스캐너 및 전시기의 성능에 따른 적절한 설정 값으로서 최적화된 Asterix CAT 240 포맷을 정의하는 방안을 연구하였다.
