旁瓣消隐技术是现代防空雷达中常用的一种空域抗干扰措施，其对脉冲式欺骗干扰的抑制尤为明显。为了最终形成航迹欺骗干扰，文中在研究旁瓣消隐系统的工作原理基础上，采用交叉极化干扰突破旁瓣消隐系统来形成假目标，利用旁瓣消隐雷达假目标检测概率作为评价指标来分析干扰效果，还分析了极化正交性及干扰功率对干扰效果的影响，最后通过仿真验证了这一方法的有效性。

Modern radar usually adopts side-lobe blanking as the air-space anti-jamming technique, SLB can suppress the impulse interference evidently. For the success of phantom track interference, the operating principle of SLB is studied, and the method of the cross-polarization interference to make the jamming signal breakthrough the SLB is adopted, and the electronic false target is formed. Is aralyzed false target detection probability to evaluate the jamming effect is broughtin and how the polarization orthogonality and interference power effect the interference. At last, the simulation proves the effectiveness of the method.
