项目摘要

In recent years, disturbance of maritime traffic has been found in coastal areas where various structures such as bridges and reclaimed airports are planned and being constructed. In this study, we have proposed a new concept of a maritime traffic survey system using a device and information processor which can operate a radar to arbitrarily record and reproduce the images. This system's reproduction ability that enabled the analysis of images by reproduction method, particularly in the laboratory, was confirmed and proved effective. In addition to the traffic analysis method that already reported, we have developed an interface connecting the radar and computer, and a processing program for the purpose of using computer to process the observation result. This development enabled the computer processing of a target on a radar PPI in the laboratory, which was difficult in the past. As a practical case, we worked on the construction of a bridge at the AKASHI Channel and studied the image processing to analyze the type of vessels from the radar image information.As a result, we succeeded in presuming the size of vessels using the formula of a linear multiple regression model. Aready, the maritime traffic analysis using this system has been applied to the aforementioned bridge to analyze the construction influence and provide the data base. It can be said that this study developed a new phase for the use of the computer analysis. The second subject of this study is the disturbance and problems of the propagation anaomalies of Decca and Loran-C navigation system, as new problem are to such electronic navigation system by maritime structures including huge bridges.

近年来，在规划和建设桥梁和填海机场等各种结构的沿海地区，已经发现海上交通受到干扰。在这项研究中，我们提出了一个新的概念，海上交通调查系统使用的设备和信息处理器，可以操作雷达任意记录和再现的图像。该系统的再现能力，使图像分析的再现方法，特别是在实验室中，被确认和证明是有效的。除已报道的交通分析方法外，我们还开发了雷达与计算机的接口和处理程序，以便用计算机处理观测结果。这一发展使得在实验室中对雷达PPI上的目标进行计算机处理成为可能，这在过去是困难的。以赤石海峡大桥的施工为例，研究了从雷达图像信息中分析船舶类型的图像处理方法，并利用线性多元回归模型的公式成功地推定了船舶的尺寸。目前，该系统已应用于该大桥的海上交通分析，为分析施工影响提供了数据基础。可以说，本研究为计算机分析的运用开辟了一个新的阶段。本研究的第二个主题是Decca和Loran-C导航系统的传播异常的干扰和问题，因为包括巨大桥梁在内的海上建筑物对这种电子导航系统提出了新的问题。
