| 摘 要： | 对于两点源干扰可以有效干扰被动雷达单脉冲测角系统。为了使被动雷达单脉冲测角系统在两点源干扰下能够有效测量目标的角度,在分析宽带噪声调频干扰信号通过接收机相位检波的输出特性基础上,应用聚类分析算法能够实现在一次测量中对一个干扰源角度的精确测量,同时也提出了动态测角时如上方法在两干扰源功率相近时测量角随机摆动的问题。通过"近值比较法"对传统聚类分析算法改进,有效解决了上述问题。仿真证明,改进后的聚类分析算法能够在1%的测角误差下稳定地跟踪一个干扰源的指向角,较大地改善了传统聚类算法,达到了抗两点源干扰的目的。

| Abstract: | ABSTRACT:Dual-source jamming can jam passive monopulse goniometry systems.In order to make the passive monopulse goniometry systems get the angle of a target under dual-source jamming,based on the analysis of output property of the broadband noise FM through phase measuring apparatus in receiver,a clustering analysis algorithm was used to track the angle of one of dual jammers steadily.And meanwhile,it showed that in this way,the dynamic metrical angles varied randomly on condition that both of the jammers ... |
