Research on Radar Cross Section Measurement Based on Near-field Imaging of Cylindrical Scanning

  • 摘要: 该文提出一种基于柱面扫描近场成像的RCS(Radar Cross Section)测量新方法:以理想的各向同性点散射中心模型为核心假设,通过详细的理论推导给出了一种具有通用性的基于柱面扫描近场成像的RCS 测量方法。该方法先得到目标的3 维雷达散射图像,再通过这些等效理想散射中心的散射场叠加获得远处散射场进而给出目标的远场RCS 值。该方法不仅能得到被测目标的3 维雷达散射图像,还能获得一定立体角域的目标远场RCS。相比只能得到2 维雷达散射图以及2 维平面角域RCS 结果的圆迹扫描测试相比,该文所提的柱面扫描测试能得到更多的目标散射信息,具有较强的实用性。仿真结果验证了新方法的可靠性。
