In Japan, large-scale earthquake disaster occurs frequently. When a large-scale earthquake disaster occurs, it becomes difficult to collect the victim’s needs and location. In addition, mobile phone and disaster prevention application cannot be used during large-scale earthquake disaster. Especially for vulnerable people, it is necessary to examine their location and needs. In this study, several reflectors with different backscattering coefficients that are observable by SAR satellites are developed. It is assumed that the reflectors will be installed by vulnerable people after the large-scale earthquake disaster. Result of analysis, reflectors with a base diameter of 50 cm and a height of 25 cm was shown to be desirable.
