무기체계의 상호운용성 측면에서 전술데이터링크는 전장정보를 공유하기 위한 필수 요소이다. 또한 비용 절감을 위해 M&S 활용이 증가됨에 따라 다중 전술데이터링크 연동이 가능한 체계 시뮬레이터가 필요하다. 그래서 M&S 장비로써 전술데이터링크인 Link-11B와 ATDL-1 연동이 가능한 다중 전술데이터링크 체계 시뮬레이터를 제안한다. 이것은 Link-11B와 ATDL-1 전술데이터링크간 정보 전달을 가능하게 하며 M&S의 표준 인터페이스인 HLA/RTI와의 연동을 통해 상호운용성을 보장한다.

ROK Forces operate Link-11, Link-16 and Korean Tactical Data Link System with Link-K(JTDLS: Joint Tactical Data Link System). As the change from Link-11 to Link-22 approaches, in the JTDLS Completed Business will be added tactical data link processing such as Link-22. In this paper, we propose the data management structure for data from multiple tactical data links. Also, we simulate to find ways to process a lot of data quickly using Shared Memory, In-Memory DB, Self Development DB in DLP, and then we confirm the result.

현대의 전술데이터링크는 전장인식에 대한 요구가 증대되어 복잡한 다중 전술데이터링크가 운용되는 추세이다. 동일 정보를 하나 이상의 경로를 통해 수신하거나 자신이 전송한 데이터를 다른 데이터링크의 중 계기를 통하여 수신하는 것을 데이터 루핑이라 하는데 루핑은 이중 표적 전시현상 또는 표적 점핑현상을 유발하고 처리기의 부하 증가로 인한 시간/자원적 낭비 등 전술데이터링크에 악영향을 미칠수 있다. 이러한 문제점을 해결하기 위해 이 논문에서는 루핑 방지 알고리즘를 제안하였고, 제안한 알고리즘이 전술 데이터링크상에서의 루핑 현상을 방지하고 효과적으로 동작할 수 있을지에 대한 성능 검증을 위하 실험을 실시하였고, 그 결과 루핑을 방지하는 것을 확인하였다.

본 논문에서는 데이터링크(Data Link)의 메시지 종류에 따른 다중 큐 처리와 종류를 고려하지 않은 단일 큐 처리의 효율적인 측면을 비교분석한다. 데이터링크는 작전에 필요한 자료의 실시간 및 근실시간 교환을 위해 사용되는 체계이다. 무인 공용 데이터링크나 전술 데이터링크는 데이터의 타입이 다양해졌고 데이터의 양이 크게 증가하였다. 이러한 이유로 다양한 데이터의 우선 순위에 따른 다중 큐 처리를 제안하여 데이터링크 개발의 방향을 제시한다.

To prepare for the network centric warfare, Korea Joint Tactical Data Link System(KJTDLS) has been developed by the South Korean military recently and its development is divided into two phases: basic and complete ones. Due to the limited bandwidth and low transmission efficiency of the developing KJTDLS (basic), lots of problems could be occurred when the TDMA protocol in Link-16 is applied. In this paper, a new dynamic TDMA frame structure for KJTDLS(basic) is proposed and the performance of the proposed is evaluated through the implementation of simulation.

In this paper, a performance comparison of dynamic TDMA and fixed TDMA in tactical data link system is conducted. The performance metric include: delay, queue size and system throughput. To perform comparison of two TDMA schemes, we adopt the modified M/D/1 queueing model. Computer simulation is also performed to verify conducted analytical results.

In this paper, we have proposed a method which can prevent data looping in multi tactical data-link operating situation. Because the situation of multi tactical data-link in Korea would be more complex than ever before, data looping is more likely to be happened. To prevent data looping, forwarder has to manage TQ(Track Quality) in forwarded track message by degrading it to enlarge correlation gate. Forwarder also has to discard useless track message which can be determined by minimum TQ value. To decide optimal formula for forwarder to degrade TQ and to determine minimum TQ, a research about track motion, correlation, TQ managing, etc in real system is necessary.

In modern warfare, the main factor of triumph is superior situation awareness which leads rapid command decision and precisely guided munition, and TDL(Tactical Data Link) is the main communicational enabler. ROK forces currently operate Link-16 with allied forces and are also developing Korean national data link, Link-K which is also planned to be cooperated with Link-16. Assigning participant and track numbers needs agreement between ROK and allied forces, but ROK forces have exclusive authority in assigning numbers in Link-K. This paper proposes the effective method of exchange participant and track numbers between Link-16 and Link-K, and applicability verification in operational test and evaluation will be also presented.

The wireless link of tactical datalink system provides a communication network to share digitalized tactical data in real-time. Also MAC(Multiple Access Control) of this system is subject to TDMA or CSMA according to a operated circumstance of target nodes to exchange the data reliably. In this paper, we verify the operability when we use CSMA scheme based on MIL-STD-188-220 in tactical datalink system which is basically designed with TDMA, and provide a mathematical analysis scheme to verify the operability and performance. Finally, by implementing CSMA scheme to a tactical datalink equipment we obtain practical results which can be compared with theoretical results.

This paper is concerned with a track management method for a naval combat system which receives the tracks information from multi-sensors and multi-tactical datalinks. Since the track management of processing the track information from diverse sources can be formulated as a data fusion problem, this paper will deal with the data fusion architecture, track association and track information determination algorithm for the track management of naval combat systems.
