有源干扰的能量在SAR图像中分布的研究
The Distribution of the Jamming Energy in SAR Image
-
摘要: 该文研究了对合成孔径雷达干扰中的能量问题, 提出了干扰能量的等同原则。指出如果雷达接收到相同能量的干扰，那么经成像处理后在雷达图像中的总干扰能量相同，不同相关性的干扰信号可以改变干扰能量在合成孔径雷达图像中的分布；这对选择合适的干扰方法和研制干扰系统具有参考意义。此外，文中还推导了合成孔径雷达干扰功率的计算公式。Abstract: This paper is about energy problem in SAR jamming. A new concept of Jamming Energy Equivalence (JEE) is presented here. The concept implies that SAR warfare is still power warfare, though SAR is interference radar. This paper indicates that different jamming methods only lead to different distribution of the jamming energy in SAR image, which is useful to the choice of jamming method and the building of jamming system. In addition, this paper gives the jamming equation of SAR.
