合成孔径雷达(SAR)干扰技术研究

首先分析 SAR系统的工作方式和成像原理 ,简述对 SAR系统实施干扰所具有的特殊性。然后 ,以对条带式 SAR实施遮盖性干扰为例 ,分析干扰的作用原理 ,推导在恒虚警准则下 ,对点目标实施遮盖性干扰所需功率的计算公式以及遮盖性干扰下的 SAR雷达方程。最后 ,进行了计算机仿真 ,并给出算例和结果分析。

Study of Jamming Technology to Synthetic Aperture Radar

By analysing the principle of imaging of Syhthetic Aperture Radar(SAR),the particularity of jamming SAR is introduced.Taking jamming to stripmap SAR as an example,how the jamming noise affects the SAR image is thoroughly analysed.And under the CFAR rule,formulae for calculating required jasmming power to mask point targets are derived,and SAR radar equation under jamming circumstances is also deduced.In the last part,Some example calculations are shown and the results are analysed.
