The purpose of this paper is to analyze the aspects of hybrid warfare and show the limits of jus in bello, a principle that evaluates the moral responsibility of the agents. As a theory of the morality of war presented in traditional warfare, the just war theory has been widely accepted. In particular, jus in bello offers the criteria of moral legitimacy regarding the actions of individuals participating in or involved in war. However, hybrid warfare, in which various aspects of warfare operate in a complex way, has obvious differences compared to traditional warfare, and this difference causes difficulties in determining the moral evaluation and attribution of responsibility for actions in war. In order to appropriately resolve the moral problems arising from hybrid warfare, it is necessary to clarify what the limitations of existing moral justification theories are. To this end, in this paper, we will first present a conceptual understanding of hybrid warfare, specify the differences from traditional warfare, and then show the limits of its application in hybrid warfare in light of the three principles that compose jus in bello.

This paper considers the problem of time difference-of-arrival(TDOA) source localization when the TDOA and angle of arrival(AOA) measurements from an airborne emitter source are subject to ground-platform sensor position. The optimization of sensors' position is a challenging problem and a solution with good localization accuracy has yet to be found. This paper proposes an estimator that can achieve these purposes and provides optimized sensor position for good localization accuracy using the proposed estimator. The developed algorithm and sensor position are then examined under the special case of a single airborne source. The theoretical developments are supported by simulations.

It is an important issue to evaluate the effectiveness of chemical warfare through modeling and simulation(M&S) technology. In this paper, we propose the M&S methodology and environment for the chemical warfare for effectiveness analysis. In detail, for modeling perspective, we propose three fundamental component models according to their behaviors, which are a chemical weapon, a detecting device system, and an engaging unit system. Among proposed models, the chemical weapon and the detecting device system models are represented by engineering-level system models, whereas the engaging unit system model are described as an engagement-level system model. For simulation perspective, we apply a hybrid simulation environment using High Level Architecture (HLA) to interoperate with the proposed engineering and engagement-level models. The proposed M&S methodology and environment enables to evaluate the effectiveness of the chemical warfare system considering the doctrines, the performance of device or weapon, and weather factors. To verify the efficiency of the proposed methodology and environment, we experimented three categorized case studies, which are related with those considering factors.

In this paper, we proposed a hybrid type robot that simultaneously surveillance and reconnaissance on the ground and in the air. It was possible to expand the surveillance and reconnaissance range by expanding the surveillance and reconnaissance area of the ground robot and quickly moving to the hidden area through the drone. First, ground robots go to mission areas through drones and perform surveillance and reconnaissance missions for urban warfare or mountainous areas. Second, drones move ground robots quickly. It transmits surveillance and reconnaissance images of ground robots to the control system and performs reconnaissance missions at the same time. Finally, in order to secure the interoperability of these hybrid robots, basic performance and environmental performance were verified. The evaluation method was tested and verified based on the KS standards.

Cyber intelligence, surveillance, and reconnaissance (ISR) has become more important than traditional military ISR. An agent used in cyber ISR resides in an enemy's networks and continually collects valuable information. Thus, this agent should be able to determine what is, and is not, useful in a short amount of time. Moreover, the agent should maintain a classification rate that is high enough to select useful data from the enemy's network. Traditional feature selection algorithms cannot comply with these requirements. Consequently, in this paper, we propose an effective hybrid feature selection method derived from the filter and wrapper methods. We illustrate the design of the proposed model and the experimental results of the performance comparison between the proposed model and the existing model.

The ROK Navy operates many war ships despite its short history. Various types of war ships, such as submarines, destroyers, frigates, corvette etc., use suitable propulsion systems for the operational requirements of each war ship. A hybrid propulsion system was introduced to change from the current mechanical propulsion system to an electric propulsion system according to the changing patterns of naval warfare, and it is expected that an integrated electric propulsion system will also be introduced. Therefore, this paper investigates the propulsion system of major ships operated by the Korean Navy, predicts the changes in future naval warfare, and proposes a propulsion system for future ships.

Millimeter wave is expected as the unlimited useful frequency resources for the next generation wireless communication services. In the past, its usage was limited to the military warfare due to lack of millimeter devices. The development of GaAs pHEMT in 1980 and the progress in the processing technologies made the new consumer wireless services possible utilizing millimeter waves. Specially, most of passive components necessary for circuit design can be integrated with GaAs pHEMTs and this removes the difficulty in assembly unavoidable in hybrid design. InP based pHEMTs developed later possess all the properties of GaAs and it shows many advantages in higher frequency applications. In this paper, the status and trends of those devices and MMICs are presented and the future developing trends is also described.

The study is based on the elaborated normative and legal documentation regulating the national security of modern Ukraine and the normative and legal documents adopted by NATO in the responding policy to the challenges that arose after 2014. The main advantages of cooperation with NATO are ensuring military security, developing army standards, improving the country's investment climate, and reducing expenditures on the army. The disadvantages of cooperation with NATO in hostilities with Russia are not highlighted. Still, defined obstacles show that Ukraine is not ready to realize entry into NATO in the short term. Such factors include weak information support, corruption, and unclear diplomatic decisions.

In this paper, a novel resource scheduling, which is used for hub network based long distance airborne tactical communication, is proposed. Recently, some countries of the world has concentrated on developing data rate and networking performance of CDL, striving to keep pace with modern warfare, which is changed into NCW. And our government has also developed the next generation high capacity CDL. In hub network, a typical communication structure of CDL, hybrid FDMA/TDMA can be considered to exchange high rate data among multiple UAVs simultaneously, within limited bandwidth. However, due to different RTT and traffic size of UAV, idle time resource and unnecessary packet transmission delay can occur. And these losses can reduce entire efficiency of hub network in long distance communication. Therefore, in this paper, we propose RTT and data traffic size based UAV scheduling, which selects time/frequency resource of UAVs by using iterative sorting algorithm. The simulation results verified that the proposed scheme improves data rate and packet delay performance in low complexity.
