摘　　要：针对功率域对抗转发式欺骗干扰问题,提出了一种基于目标功率模型的对抗措施。根据真实目标回波功率随距离变化规律,结合目标RCS起伏模型,建立目标回波功率模型。基于功率模型,根据错判概率设定判定门限,来区分真假目标并将假目标剔除。仿真结果表明,在目标满足斯威林I、II模型的情况下,错判概率为10-7、10-10、10-13时对应的门限,在目标与雷达距离大于错判距离时能够有效区别真假目标。在距离大于25 m时,三种门限都能有效区分真假目标。This paper proposes a method against deception jamming based on target power model to solve the problem of deception jamming in power domain.According to the variation regular of true target echo power with distance,this paper builds a target echo power model based on target RCS model.This model can distinguish true target and false target through threshold based on the error probability.The simulation results show the model can identify jamming with distance greater than the error distance in the thresholds which is based on the error probability 10-7,10-10,10-13 when targets accord with SwerlingⅠ/Ⅱmodel.When distance is greater than 25 m,three kinds of threshold all can identify deception jamming.
