ELECTROMAGNETIC SPECTRUM SECURITY RESEARCH PROGRAM
Center for Global Security
Outline of Research
Electromagnetic spectrum has been used for command/ communication, and warning / surveillance. It is now recognized as a major operational domain situated on the frontline of the offense – defense dynamic in today’s warfare.
Electromagnetic Spectrum Security Research Project
We are working on the following projects.
| 1 | Research on a simple method for measuring radar cross-section
(1) Overview
Radar is a device that uses radio waves to detect targets and is used in both everyday items and defense equipment. Radar cross-section generally increases in proportion to an object’s size; the larger the value, the easier it is to detect the target. When measuring radar cross-section outdoors, various sources of noise and other reflections can interfere with the results, so evaluations are often conducted indoors. However, while indoor measurements save space, they fail to satisfy the far-field conditions required for radar cross-section measurements. Consequently, although various measures are necessary, this leads to a complex measurement system. Therefore, in this study, we propose a measurement system that is as simple as possible, tailored to the size and dimensions of the object.
