Evaluation of Luneberg Lens Focusing Performance in a Finite Size Anechoic

In the coastal fishery, it is becoming more important to measure the position of fishing gear such as setnet using SAR satellites. In this study, we studied the retroreflective structure using the Luneberg lens in order to detect the floating buoys such as fishing gear with the SAR satellite radar. We report on our research on a method for evaluating the light gathering performance of Luneberg lenses in an anechoic chamber of finite size.
