摘要
本文首先从信号—干扰功率比 (信干比 )的角度分析了合成孔径雷达 (SAR)噪声干扰的效果及特点 ,分析了对SAR系统实施噪声干扰的特殊性以及影响SAR噪声干扰效果的因素 .然后 ,利用机载SAR原始数据进行了噪声干扰仿真实验 。
The effectiveness and characteristics of noise jamming to synthetic aperture radar (SAR) are firstly analyzed through signal-to-jam ratio (SIR) in this paper, and the particularity of jamming a SAR and the factors which impact the effectiveness of noise jamming are studied. Furthermore, the simulation of noise jamming to airborne SAR is executed through SAR raw data, and the imitated results are given and analyzed.
