在日本，老年人占人口的比例是世界上任何国家中最高的。当大规模地震灾害发生时，大量人员伤亡尤其发生在老年人中。许多人在身体或精神上都很脆弱，在救灾的不同阶段需要帮助，包括救援、疏散和住在疏散中心。然而，老年人的数量越来越多，使得在灾难发生后难以迅速收集有关他们所在位置的信息并评估他们的需求。作者正在制定一项提案，通过部署可以在合成孔径雷达（SAR）卫星图像中检测到的雷达反射器，使弱势群体能够在灾害发生后向响应团队发出他们的位置和需求。本研究的目的是开发一种雷达反射器套件，老年人可以很容易地组装，以使这一建议在实践中可行。三个版本的反射器进行了检测，并要求老年人的样本组装套件，并提供反馈意见，他们遇到的问题，并就他们在使用反射器在发生大规模灾难的兴趣。
In Japan, older adults account for the highest proportion of the population of any country in the world. When large-scale earthquake disasters strike, large numbers of casualties are known to particularly occur among seniors. Many are physically or mentally vulnerable and require assistance during the different phases of disaster response, including rescue, evacuation, and living in an evacuation center. However, the growing number of older adults has made it difficult, after a disaster, to quickly gather information on their locations and assess their needs. The authors are developing a proposal to enable vulnerable people to signal their location and needs in the aftermath of a disaster to response teams by deploying radar reflectors that can be detected in synthetic aperture radar (SAR) satellite imagery. The purpose of this study was to develop a radar reflector kit that seniors could easily assemble in order to make this proposal feasible in practice. Three versions of the reflector were tested for detectability, and a sample of older adults was asked to assemble the kits and provide feedback regarding problems they encountered and regarding their interest in using the reflectors in the event of a large-scale disaster.
