Unmanned Aerial Vehicles (UAVs) have been considered as valuable aerial reconnaissance systems and our army wants capability-enhanced UAVs installed in our territory, hoping that the UAVs will provide enemy information in detail. The enemy information acqcuired by UAVs would be shared by our army's legacy systems. In this article, we made a research on the interoperability between UAVs and Ground Fighting Vehicles (GFVs), laying emphasis on what kinds of tactical information could be exchanged by two different weapon systems. Also, it needs to be addressed that their upper-level commanding systems play a significant role in such operation.

One of various main jobs in the design of a new tactical vehicle is to develop the lightest chassis parts satisfying the required durability target. In this study, the analytic methods to reduce the size and weight of a lower control arm and chassis frame of a Korean light tactical vehicle are presented. Topology optimization by ATOM (Abaqus Topology Optimization Module) is applied to find the optimal design of the suspension arm with volume and displacement constraints satisfied. In case of chassis frame, the light-weight optimization process associated with design sensitivity method is developed using Isight and ABAQUS. By these analytic methods we can provide design engineers with guides to where and how much the design changes should be made.

Commanders want to receive quickly scientific and analytic results about the battlefield situation. Unfortunately, decision support system of Army Tactical Command Information System(ATCIS) is restricted to message procedures and searching function based on manual work. In this paper, we propose applying Data Mining to ATCIS for supporting rapid decision making based on the scientific and analytic method. The purpose of this proposal is to efficiently execute the tactical planning and employment of the subordinate units in order to achieve the mission.

This paper describe the method for maintaining initial azimuth of tactical grade IMU. The proposed method uses the zero velocity update (ZUPT) algorithm based on Kalman filter and the azimuth information previously obtained through transfer alignment. ZUPT technique can estimate and correct navigation attitude errors using the observed velocity error without the need of other sensors. Also, ZUPT combined pre-obtained azimuth information allows to maintain initial azimuth for tactical grade IMU. We verify the performance improvement of the proposed azimuth maintaining method by simulation and test.

Discrete noise signals from a small scale tactical unmanned aerial vehicle(UAV) propeller were predicted numerically using time domain approach. Two-bladed 29 inch propeller in diameter and 150 kgf in gross weight were used for main parameters of the UAV based on the actual size of the similar scale vehicle. Panel method and Farassat formula A1 were adopted for aerodynamic and aeroacoustic analysis respectively. Time domain signals of both thickness and loading noises were transformed into frequency domain to analyze the discrete noise characteristics. Directivity pattern in a plane perpendicular to the rotating disc plane and attenuation of noise intensity according to double distance were also presented.

In this paper, we propose a stable mutual authentication protocol between unmanned combat systems in tactical wireless networks where long distance communications are not always guaranteed due to a poor channel condition. The proposed protocol generates an authentication code using hash collision of arbitrarily selected random data. The authentication requester encrypts and transmits it to the authenticator. They performs authentication by sharing the valid authentication code. We analyze the safety of the proposed method for various attack scenarios.

This report shows the analysis and design of tactical decision automation procedure and the result of core algorithm. Expecially scheme of analysis and design includes result of tactical decision supporting procedure analysis for target engagement to fire in refer to AFATDS. Tactical decision automation procedure has three phases like target analysis, target priority, fire unit decision, fire method and attack method. Target analysis creates base information to decide priorities and attack methods through target activity, size and protection status. Target priority and fire unit decision judge target priority and fire unit with unit status and operation mission basis of target priority. Fire unit and Attack method decide fire style according to the kind of fire and ammunition for effective firing achievement. Finally, we show the effective tactical decision automation procedure through making the algorithm of priority and air control.

In this paper, we analyses transmission performance of interleaving for cipher communication in TDMA STD DP mode of aerial tactical communication link. In LINK16 link we present about transmission architecture of STD DP mode and study an effect of interleaving, the capability of crypto synchronization pattern, and a quality of degraded effect of transmission communication during crypto communication.

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.
