摘要: 针对传统噪声卷积调制的合成孔径雷达(SAR)虚假信号方法存在距离向位置滞后、方位向压制范围不可控的缺陷，该文提出了一种改进的虚假信号生成方法。该方法首先对截获信号作快时间域移频调制，以控制掩护面的距离向位置；接着将其与经过了慢时间域滤波处理的噪声模板卷积，以控制掩护面积。理论分析与仿真结果表明，相比于传统噪声卷积调制，该文所提的方法可有效控制掩护面的距离向位置和面积，即使在较大侦察误差下仍能对局部场景实施掩护，提高了相同条件下的干扰能量利用率，对实际工程应用具有一定的参考价值。Abstract: Suppression position of the traditional noise convolution modulation Synthetic Aperture Radar (SAR) jamming lags behind in range and suppression area in azimuth is uncontrollable. Considering this defect, an enhanced jamming method is proposed herein. First, the frequency of the intercepted signal is shifted in fast-time to control the suppression position in range. Then, the convolution with the noise is implemented, which has been filtered in slow-time, to control the suppression area in azimuth. Theoretical analysis and simulation results demonstrate that the proposed jamming method can efficiently control the jamming position in range and suppression area when compared with the traditional noise convolution modulation jamming. Even if some reconnaissance errors exist, the local scenario can still be shielded effectively. Furthermore, the utilization efficiency of jamming energy is also improved under the same condition, which will provide some reference values and inputs for engineering applications.
