典型海况下浮标SART天线辐射性能分析

In the marine emergency rescue,Search and Rescue Radar Transponder (SART) is mainly responsible for important functions to send rescue ships and aircraft direction finding and range information. Under different sea conditions, especially in adverse sea conditions, the merits of its antenna performance parameters is directly related to the success and timeliness of the rescue, so the research is very important. To address this problem, create a three-dimensional typical sea state models and SART antenna, and use numerical simulation of electromagnetic simulation software ship EDF,then get influence on radiation pattern of SART antenna in different sea conditions, different buoy height cases.And provide a basis for improvement and validation methods to design the antenna in adverse sea conditions.
