| 摘 要： | 超宽带SAR通过二维压缩处理获得了高处理增益，大大提高了其抗干扰能力，传统的干扰技术已经无法对超宽带SAR实现有效干扰。利用雷达发射信号与噪声函数进行复卷积形成的干扰信号，在雷达信号处理中可以获得与目标回波信号相当的处理增益，从而可以大大降低对干扰功率的要求，因此在超宽带SAR干扰技术中具有很大的应用潜力。噪声函数形式不同，其干扰效果也有明显的区别。通过理论分析，探讨了基于复卷积的干扰技术理论基础及噪声函数形式对干扰效果的影响，并通过仿真实验验证了该方法的有效性。

| Abstract: | Ultra wide band(UWB) synthetic aperture radar(SAR) can get high gain by two dimensional compression processing,so the capability of count electronic counter measures(CECM) is improved greatly.The effect of traditional electronic counter measures(ECM) is limited and to some extent it is useless.The jamming signal is generated based on the convolution of the radar signal and the jamming function.The jamming signal can get comparative gain when it is processed by the radar receiver.In this way the jamming effe... |
