基于多输入多输出合成孔径雷达的二维混合基线抗欺骗干扰方法
|
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。
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 multichannel signal orthogonal, we propose the detection of deceptive jamming phenomenon by employing multidimensional 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.
