摘要随着我国综合国力的迅速增强，我国的国家发展战略已经逐渐由陆地方向向海洋方向倾斜，对海洋的开发业已已经从近海走向远洋。同样随着自身海洋经济区域的快速扩 大，我国海洋安全问题日益突出。我国拥有漫长的海岸线，拥有巨大的领海面积和专属 海洋经济区，安全领域的任务范围大，方向多，面积广，面临着多方面威胁的严峻挑战。 介于这样的应用背景，毫米波段雷达在海域上的使用就被摆放在了突出的位置。由此， 水面目标的毫米波辐射建模、研究等课题便成为了该波段被动雷达系统的研制、开发、 应用等项目的核心内容。 

 水面军事目标以金属材料制成的居多，如作战、支援舰艇，两栖装甲车辆等等。毫米波探测器具有体积小重量轻等优点，已经在地空金属目标探测领域得到了广泛开发与 应用，而水面金属目标的探测则缺少相关研究与文献支持。因此，展开对水面金属目标 相关的毫米波辐射特性研究，具有重大意义，尤其是建立相关的目标检测数据库。以上 工作对于我国海洋军事监测体系的建立与完善具有重要意义。 79489

Title Modeling and Experimental Study of Millimeter    Wave Radiation for Metal Targets on the Surface of the Water 

Abstract With the rapid increase of China's comprehensive national strength, China's national development strategy has gradually tilted from the direction of the land to the ocean, the development of the ocean industry has already gone from offshore。 Also with the rapid expansion of its own marine economic region, China's maritime security issues have become increasingly prominent。 China has a long coastline, has a huge area of territorial waters and exclusive Marine Economic Zone, a large number of tasks in the field of security, direction, and a wide area, faced with a number of serious challenges。 Between this application background, the use of millimeter wave band radar in the sea is placed in a prominent position。 As a result, the modeling and research of millimeter wave radiation on the surface of the water target has become the core content of the research, development and application of the passive radar system。

The majority of metal materials are made of metal materials, such as combat, support vessels, amphibious armored vehicles and so on。 Millimeter wave detector has the advantages of small volume, light weight, etc。, and has in air ground metal target detection field has been widely developed and applied, and detection of surface metal targets is the lack of related research and literature support。 Therefore, it is of great significance to study the millimeter wave radiation characteristics related to surface metal objects, especially to establish the relevant  target detection database。 The above work is of great significance to the establishment and improvement of China's marine military monitoring system。

In this paper, the millimeter wave radiation of metal target is modeled, and the analysis and verification are carried out by combining with the practical and experimental simulation environment。 In order to system analysis and modeling methods, the following items: first of all, exposition and introduction of microwave radiation principle; and then introduces the millimeter wave radiometer system and radiometer calibration method, the radiation characteristics of several typical surface metal target were modeling, and field testing of the actual。 By comparing the simulation results with the data obtained, the experimental experience is summarized, and the experiment and application theory are verified。
