从海湾战争可知，现代战争中，雷达电子战是决定战争胜负的重要因素。故在雷达电子战技术的研究开发中，有效地获得准确评估所需数据至关重要。然而，为获取这些数据而进行的室外试验，因受环境等因素的限制，难以确保其再现性。此外，日本国内当时高精度室内测试设备尚未问世 From the Gulf War we can see that in modern warfare, the electronic warfare of radar is an important factor that determines the outcome of the war. Therefore, in the research and development of radar electronic warfare technology, it is very important to effectively obtain the data needed for accurate assessment. However, the outdoor test to obtain these data is difficult to ensure the reproducibility due to the environmental factors. In addition, high-precision indoor test equipment in Japan was not yet available
