3차원 레이다는 거리, 방위각 및 고도에 대한 3차원 첩보를 확보함으로써 신속하고 정확한 표적 탐지 및 추적은 물론 기능 및 운용에서도 2차원 레이다 보다 유리합니다. 현재 우리는 2차원 레이다의 국내개발을 통해 전지역 대공 감시를 수행하려는 시점에서 이른 감이 있지만, 장차 국내 레이다 기술발전 및 방공무기의 국내개발과 대공무기체계의 효율성을 고려하면 3차원 레이다에도 관심을 기울여야 합니다

As most landscape drawings tend to be recorded in electronic format, the need for layer standards is growing. While the categorization system of planting drawings has been progressing, landscape facility drawings are being delayed. So, the purpose of this study was to establish the categorization system of computerized landscape facility drawing documents. In the beginning of this study, it found that the layer categorization system of "The Standards of Construction CALS/EC computerized drawings v1. 1" and "The submit instructions of electronic design documents" are not suitable for the landscape facility drawings. 1,154 drawings drawn by 10 landscape architect offices were used to analyze the current layer categorization status. As a result, it found that "The Standards of Construction CALS/EC computerized drawings v1. 1" were not introduced in landscape facility drawings and 46% of layers were produced indefinitely. The new layer categorization system consisting of 15 facility items was drawn by applying the ISO construction information categorization system. The new layer categorization system is set on the basis of the legal code, landscape design standards, and design guidelines of public institutions. This new layer categorization system is expected to propagate at the landscape architect offices in the early.

Institutional repository has been regarded as core facilities of research libraries to realize open access by collecting, preserving, distributing of intellectual asset what institution has created. In our country, many universities and research institutions are trying to introduce institutional repository system. But almost universities not only take the negative attitude to manage properly, but also never give basic training to staff members who take over institutional repository job. This study brightens up the current status of Korean training system and compares the British and Japanese cases what shows diverse advanced managing cases. Furthermore, by putting together demands of hands-on workers, suggest direction of future institutional repository staff training system. First, institutional repository staff training system has to suggest strategies to induce strong support from institution. Second, it has to give not only courses about content collecting and registering, but also practical training. Finally, the program for enhancing system management technology has to be provided, and the place where technical staffs can share their system information mutually has to be provided.

The system performance of naval multi function radar is affected by radar beam operation. Multi f function radar has to operate complicated beam better than search radar and tracking radar which have single operation. This paper describes fabricating analysis tool for the verification method for system performance of naval multi function radar. We composed the model that naval ship with MFR and radar which are detecting targets to verification the system performance. The targets are composed anti-aircraft and anti-ship. We integrate each model and make naval MFR simulator that applied resource management of track beam and search beam. We verify analysis tool by simulation in operating scenario after adjusting system parameter to analysis tool.

JSTARS는 일명 Joint STARS라고 하며 원거리에서 고정 및 이동 지상표적을 탐지, 추적하여 그 위치를 지상 지휘관과 공습항공기에 통보함으로써 적을 제압하는 미국 육.공군 합동 지휘통제 체계입니다 이 체계의 개발 동기는 서유럽에 대한 바르샤바군의 공격을 저지하기 위해, 원거리에서 나토(NATO)군이 재래식 무기를 사용하는데 표적 공격의 정확성이 필요하였기 때문입니다

A synthetic aperture radar (SAR) system can provide all-weather, day and night imaging capability, and thus, is very useful in surveillance for both civil and military applications. In this paper, the X-band spaceborne SAR system design procedure is introduced with the key design parameters for mission and system requirements characterized by the small satellite platform. The SAR imaging mode design technique is presented, and the design results are analyzed for standard mode performance evaluation. In line with the system requirements, the X-band SAR payload and ground reception/processing sub-systems are presented with the key design results and image applications examples. The designed small satellite SAR system shows the wide range of imaging capability, and proves to be an effective surveillance system in light-weight, high-performance and cost-effective points of view.

One of the critical items in radar testing is the ability to evaluate the performance of radar systems under real operational environments. But it takes lots of time and cost to operate real targets and analyze the test results due to a large amount of data based on these complicated environments. In this paper, the Radar Simulative T&E Lab. is introduced, and the test and analysis results of the developing radar for predicting the radar system performance are described in the Radar Simulative T&E Lab. This laboratory could be used to test the far-field characteristics of antenna radiation pattern and to perform an effective radar system test and evaluation using a simulative target generator under a low cost repeating test situation.
