In this paper, We propose a new super resolution method using a Generative Adversarial Network(GAN). Several super resolution techniques, including interpolation, CNN(Convolutional Neural Network), and GAN, have been proposed. Among them, GAN is the most preferred because of its good performance in image synthesis. Consequently, there have been many attempts to improve the super resolution quality by changing the network structure and loss function of GAN’s Generator, but the focus of improvement was not focused on the discriminator. The findings of the present study confirmed that the U-Net structure and the auxiliary classifier structure for image rotation, which were presented in other papers, had a positive effect on super-resolution network.

MIDS LVT is communication equipment mounted with Link-16-based weapon systems to provide the Link-16 operating environment between weapon systems. Currently, the military operates the MIDS LVT BU1, but it will be changed to the BU2 and JTRS according to the performance improvement. The communication interface, message data format, and message composition of the MIDS LVT are different depending on the platform family (BU1/BU2/JTRS) and type (A,D,J). In this paper, we propose a framework based emulator design and implementation method that considers the MIDS LVT platform extension to improve these problems. In consideration of the quality attributes of the sw architecture, we designed a common based framework for modifiability, reusability, and extensibility. The MIDS LVT emulator comprises the MIDS LVT emulator processing, link interface processing, and monitoring tool. The MIDS LVT emulator was implemented by deriving and improving functions through the analysis of the functions of the previously developed overseas tools. Through the development of the MIDS LVT emulator, it can be used to develop and verify the developed Link-16 host system.

Identification of Friend or Foe(IFF) is a function of military surveillance system used to identify whether the monitored object is an ally or an enemy, these system are installed in fighters, ships, and interceptors among others. The United States plans to suspend the Mode-4 identification system and apply Mode-5 from July 2020 forward. The transition to Mode-5 is inevitable as it ensures the interoperability of peer identification systems used in the Republic of Korea’s military operations with the US as well as other NATO member states. If the IFF function found in control centers and multi-function radars is changed in regional air defense weapons systems, revalidation of these weapons systems is required to ensure stability and correct function. Therefore, a multi-function radar simulator is vital use in interface verification, unit tests, and integrated tests before evaluation of the new systems can be completed. This paper presents the design of a simulator for mode-5 performance testing and improvement.
Development of Reconfigurable Tactical Operation Display Framework by Battery and Battalion
Sangtae Lee, Seungyoung Lee, SoungHyouk Wi, Kyutae Cho
The tactical operation centers of future anti-aircraft missile systems provide the environment for the research on future air threats, tactical information, integrated battlefield environment creation and management, engagement control and command and control algorithms. To develop the key functional elements of integrated battlefield situation creation and processing and tactical operation automation processing operations, battery/battalion tactical operation control and reconfiguration design software are required. Therefore, the algorithm software of each function and the tactical operation display software and link software for interworking between equipment were developed as reconfigurable through a data-centric design. In this paper, a tactical operation display framework that can be reconfigured on the operation display of the tactical operations according to the battery/battalion is introduced. This tactical operation display framework was used to develop a common data model design for the reconfigurable structure of multi-role tactical operations with battery / battalion and mission views, and a display configuration tool that provides a tactical operation display framework for view development was also developed using the MVC pattern. If the tactical operation display framework is used, it will be possible to reuse the view design through the common base structure, and a view that can be reconfigured easily and quickly will also be developed.
