近年来随着雷达技术的不断发展,雷达极化特性在目标特征提取和识别中应用越来越广泛,尤其在与高分辨技术的结合,成为现代雷达发展的重要方向之一。文中以步进频率宽带雷达体制下的弹道导弹中段目标为例,提出了一种基于FEKO仿真软件获取目标全极化回波数据,进而生成目标全极化HRRP的方法。结果显示,该方法实现简单、效率高、成本低,可以成功实现目标全极化HRRP的生成。

With continuous development of radar technology, radar polarization characteristics have been more and more widely applied in target feature extraction and recognition in recent years, especially, continuous development of high resolution imaging and complete polarization makes them become one of developing tendencies for modern radar. Warhead target in ballistic missile midcourse under the system of step frequency broadband radar, as an example, has been researched in this paper. Then, a method of obtaining complete polarization data of targets based on FEKO and generating complete polarization HRRP of targets has been proposed. Results show that this method is simple, highly efficient and substantial. The realization of complete polarization HRRP is achieved successfully.
