6-DOF flight simulation program is most generally used M&S tool in domestic missile development procedure. The 6-DOF M&S method, however, cannot validate the performance of a imaging seeker-adopted missile in various conditions. A M&S tool for the analysis of the integrated-flight simulation is required since the tracking performance of the imaging seeker is highly dependent on the missile maneuvering, which introduces the displacement and rotation of the target in the seeker imagery. Through the development of the $3^{rd}$ generation anti-tank missile, Raybolt, the integrated-flight M&S tool was developed and applied to the missile configuration design. It integrates synthetic image generation S/W, imaging tracker, and flight simulation program and computes the main system performance criteria, hit probability by Monte-Carlo Simulation. In this paper, the issues in the $3^{rd}$ generation anti-tank missile configuration and the integrated-flight M&S method and results are described.

In government procurement programs, cost estimation and analysis support funding decisions and are the basis for other major decisions, too. Such estimating and analyzing the cost of the weapon systems are crucial in execution of the defense budget. However, existing cost estimations and analyses have focused on domestic R&D projects, thus those are not valid in application to foreign weapon acquisitions. This study aims at foreign weapon systems that are acquired from Direct Commercial Sales. Because the data for price estimation of a foreign weapon is usually not available, we suggest a price estimation model based on performance factors of the weapon. In this study, the proper price of the weapon system is estimated using the parametric cost estimating model. Using the data of helicopter-launched anti-tank guided missiles worldwide, we analyze the effect of each performance factor on the weapon system price by regression analysis, and use step-wise and ridge regression analysis to remove multi-collinearity. This study hopefully contributes to more reasonable decision making on proper price of weapons.

선진 항공기 개발국들은 인간공학적인 조종사-항공기 인터페이스의 중요성을 제2차 대전시에 깊이 인식하였으며, 현재는 개발되고 있는 항공기별로 40~50명의 연구원들이 인간공학적 연구를 하고 있다. 또한 항공기 무기체계 개발과 마찬가지로 전차, 군함, 잠수함, 유도 미사일 등의 무기체계에도 반드시 사용자의 인간 공학적인 요소들이 적용될때, 성능이 최대로 보장될 것이다

The kill probability of a missile depends on guidance error, warhead performance, and etc. In this paper, we analyzed the kill probability of anti-tank missile in a new approach. Under the condition that the missile hit the target, we studied the effect of angle of attack and impact angle. High impact angle increase the probability that the missile hits the upper armour which is relatively weaker, while high angle of attack at the impact instant decreases the effectiveness of the jet induced by the warhead. We proposed a way to increase the capability of penetration by analyzing the interrelation between impact angle and angle of attack.

The principle of Effective Based Operation applied to the Korean Theater resulted in measurable effects to win the minimum battle. Based on the finding, this study recommends the effect analysis methodology under the V-C interoperability system to acquire a weapon system. This method is followed as below; to confirm the effect data on the organized weapon system, to set MOE, MOP and effect considering the purpose of the analysis, to apply the appropriate operational concept and scenario on the weapon system, and then the available C Model is after action reviewed, adjusted, and given feedback. The V-C interoperability system enables to perform the real-time combat experiment under the virtual synthesized battlefield circumstances. The defensive battle organization and displacement of the future anti-tank guided weapon system was considered in the modeling process. Scenario was written, which encompasses company-level units and the battalion-level operation. Then the available AWAM was embodied and effect-analyzed, which formed the foundation of SBA.

In this paper, we proposed a method for eliminating aiming error of unguided anti-tank rocket using improved target tracking. Since predicted fire is necessary to hit moving targets with unguided rockets, a method was proposed to estimate the position and velocity of target using fire control system. However, such a method has a problem that the hit rate may be lowered due to the aiming error of the shooter. In order to solve this problem, we used an image-based target tracking method to correct error caused by the shooter. We also proposed a robust tracking method based on TLD(Tracking Learning Detection) considering characteristics of the FCS(Fire Control System) devices. To verify the performance of our proposed algorithm, we measured the target velocity using GPS and compared it with our estimation. It is proved that our method is robust to shooter's aiming error.

다련장로켓은 기습적 대량화력의 집중, 기동성, 사거리의 손쉬운 증대가능성의 장점을 가지고 있어 제2차 세계대전에서 처음 등장한 이후 대부분의 국가에서 야전 포병의 기본 무기체계로서 발전되어 왔다. 전세계 40개국 이상에서 사용하고 있는 다련장로켓은 유도방법, 탑재차량, 전자자동제어 분야의 발달로 점차 대구경화하여 사거리가 증대되고 있으며 탄두의 위력도 증대 다양화되고 있다. 현재까지 개발된 다련장로켓 중에서 가장 우수한 무기체계중의 하나로 알려진 MLRS는 미국을 비롯한 세계 13개국에서 채택하고 있으며 우리나라에서도 장비도입을 진행 중에 있다.현재 구룡을 생산하고있는 (주)한화에서는 이 MLRS가 차기 주력제품이 될것으로 판단하여 미제 사거리연장형(ER-MLRS)와 유사한 한국형 대구경 다련장로켓을 거룡이라고 명명하고 '93년부터 기초연구를 진행해 왓다. '94년 7월 첫 지상연소시험을 수행한 이후 현재까지 8기의 지상연소시험을 마쳤고, 지난 9월에는 비행용로켓 2발을 제작 비행 시험을 실시한 바 있다.본 논문에서는 미제 MLRS의 구성,제원,특성을 추진기관 중심으로 알아보고,자체 연구개발중에 있는 거룡 로켓의 추진기관 개발 현황을 지상연소시험을 중심으로 간단히 요약하고 미제와 성능을 비교해 보았다.향후 지속적으로 추진기관의 성능 개량을 추진할 계획으로 있으나 현재까지의 진행결과로 볼 때 추진기관의 개발은 문제가 없고, 대구경 다련장로켓탄 전체도 국내기술로 충분히 개발이 가능한것으로 판단된다.
