摘要: 针对采用有序统计类恒虚警检测的线性调频脉冲压缩雷达,提出了一种专门的多假目标产生方法。根据有序统计类恒虚警检测原理进行干扰假目标设计,在此基础上提出具有移频特征消隐的多载波干扰方法;针对有序统计类恒虚警检测的特点,对干扰参数进行设置,在真实目标的左右检测单元产生了数量、幅度、空间分布可控的多假目标。仿真结果表明,该干扰方法可以有效降低目标在雷达检测端被发现的概率。

Abstract: A multi-false-target jamming method is proposed for the linear frequency modulation pulse compression radar with order-statistic(OS) CFAR detector. According to the principle of OS-CFAR detector, a multi-carrier and blanking shift-frequency shifting Jamming method is proposed. Some key parameters are set by using the characteristics of OS-CFAR. As a result, multiple false targets with the quantity, amplitude and space distribution which can be controlled are produced around the true target. The simulated results show that the jamming method can be used to reduce the detection probability of target effectively. Key
