摘　　要：为了解决雷达抗压制干扰难题,提出了一种基于干扰成像对消的抗压制干扰新方法。基于虚拟透镜成像技术,采用和/差波束成像精确测定干扰角度坐标。根据测定的干扰坐标,采用点目标拟合压制干扰源,生成对应的阵列接收信号。通过对拟合的干扰及阵列信号进行干扰成像重建和对消,进而消除或降低压制干扰对目标检测的影响。最后进行了抗干扰仿真,仿真结果表明,所提方法能够有效对抗副瓣干扰和近主瓣干扰,同时对主瓣干扰也具有一定的对抗效果。In order to solve the problem of radar anti-suppressive jamming,a new method based on jamming imaging cancellation is proposed.Sum/difference beam imaging technology is used to accurately measure the jamming angle coordinates based on virtual lens imaging technology.According to the measured jamming coordinates,the jamming source is fitted.Then the corresponding array receiving signal can be generated.Through the jamming imaging reconstruction and cancellation of the fitted jamming and array signal,the influence of suppressive jamming on target detection can be eliminated or reduced.Finally,the anti-jamming simulation is carried out.The simulation results show that the new method can effectively counter sidelobe jamming and near main-lobe jamming.For the main-lobe jamming,the new method also has a certain effect.
