基于SAR图像的欺骗式干扰效果评估研究

SAR具有较强的抗干扰性能,欺骗式干扰是对抗SAR的重要手段。欺骗式干扰的有效性主要取决于欺骗假目标的逼真程度,假目标越逼真,ATR系统就越难以将其从真实目标中识别出来,欺骗干扰效果也就越好。在此基础上,提出了一种基于SAR图像的欺骗式干扰效果评估系统,该系统可以对欺骗假目标的模拟逼真程度进行定量评估。

Effect evaluation for deception jamming based on SAR image

SAR has the great capability of ECCM,and the deception jamming is an important measure against SAR.The fidelity of decoy targets determines the validity of deception jamming.The more lifelike the decoy targets are,the more difficult the ATR system recognise them from true targets,so the result of deception jamming is better.Therefore an effect evaluation system for the deception jamming is proposed based on SAR images,which can quantificationally evaluate the fidelity of the decoy targets.
