| 摘 要： | 计算机仿真是研究频率捷变雷达对抗的有效方法,通过频率捷变雷达(FAR)和干扰的动态对抗仿真来反映FAR(或干扰)的性能。首先介绍了多种频率捷变雷达干扰技术;然后,以能量准则为基础,根据雷达方程和干扰方程给出了FAR的目标检测模型,模型中将FAR和干扰在频域对抗体现在干扰有效频带上,并给出了上述几种干扰情况下干扰有效频带的计算模型;最后给出了不同情况下宽带阻塞式干扰、扫频干扰和转发式瞄准干扰对FAR的干扰性能。仿真结果表明FAR并不是不能干扰,其干扰性能不仅与干扰方式有关,而且与干扰参数有密切关系。

| Abstract: | Computer simulation is a valid method to study the performance of frequency agile radar(FAR) or jamming in the ECM circumstance.Firstly introduces the jamming techniques against FAR.Secondly,according to radar equation and jamming equation,presents the detection simulation model of the FAR based on the rule of energy in which the Effective Jamming Band(EJB) is used to represent the ECM in the frequency domain,then describes the EJB calculation model of jamming.Lastly lists the jamming performance to FAR of wideband barrage jamming,sweep-spot jamming and repeating spot jamming in different conditions,and the simulation result shows that FAR can be interfered,and that the interfering effect depends on the jamming method and the jamming parameter. |
