| 摘 要： | 针对距离延时和方位多普勒频率调制两类合成孔径雷达(SAR)欺骗干扰问题，该文提出一种基于多输入多输出合成孔径雷达(MIMO-SAR)的2维混合基线抗欺骗干扰方法。该方法采用基于MIMO-SAR的相位编码方案，使得多通道信号正交，利用多维相位信息识别欺骗干扰，通过相位补偿抑制干扰目标，从而提升雷达抗欺骗干扰能力。该文采用雷达抗干扰改善因子进行定量效果评估，在平台空间受限的条件下，该文方法比传统单发多收系统的雷达抗干扰改善因子提升3倍。仿真实验结果证明了该方法的有效性与正确性。

| Abstract: | A novel approach using two-dimensional mixed baseline based on Multi-Input Multi-Output Synthetic Aperture Radar (MIMO-SAR) has been proposed for range delay and azimuth Doppler frequency modulation used in deceptive jamming. Based on MIMO-SAR phase coding method, which makes the multi-channel signal orthogonal, we propose the detection of deceptive jamming phenomenon by employing multi-dimensional phase information, and suppress the jamming targets via phase compensation to improve the ability of countering deceptive jamming. Moreover, we utilize radar anti-jamming improvement factor as a quantitative evaluating index. In the limited platform space, the radar anti-jamming improvement factor of the proposed method is three times greater than that of conventional single-input multi-output systems. Experimental results demonstrate the validity of our method. |
