摘　　要：雷达信号分选是雷达对抗中一个重要的组成部分,只有从随即交迭的信号流中分选出各个雷达脉冲序列之后才能进行信号参数的测量、分析、识别。目前基于PRI参数提出很多分选方法,针对各种方法的优缺点,研究了一种基于SDIF算法和序列相关法联合检测的被动雷达信息处理系统信号分选跟踪机,经仿真证明,基于SDIF与序列相关法的联合检测增加了检测概率,具有较好的鲁棒性,可以较好地对空间多部不同雷达信号进行准确分选,正确给出跟踪波门。该信号分选跟踪机已在工程中应用。Radar signal sorting is an important part of radar countermeasure,only after sorting the overlapping radar pulse signals,the measurement,analysis and target recognition of the signal parameters can be accomplished.Many sorting methods are proposed based on PRI parameter now.The advantages and disadvantages of those methods are studied,a radar signal sorting and tracking design of the passive radar information processing system based on the united detection of the SDIF and the serial correlation methods is introduced.The simulation results show the united detection increases the probability of detection,has good robustness,can sort various radar signals accurately in the space,and gives correct tracking gate.
