导引头的抗干扰性能通常是通过地面实验来验证的.为了尽可能地仿真实际的干扰环境,需要研制大量的干扰设备和相应的仿真设备.而战场上的干扰环境又千变万化,技术发展十分迅速,这就要求仿真设备不断更新,极大地增加了研制周期和成本.探讨了导引头抗干扰的数字仿真技术,使抗干扰性能得到定量的评估.讨论了非成像光电寻的导引头的抗干扰数字仿真.

As usually the evaluating EOCM for seeker processes through experiment in Laboratory or test in out-ground. So that a lot of ECM and simulation equipments have equipped necessarily. But in further war status, the ECM and EOCM techniques rapidly develop with variability environment, which enhances a great cost of experiment research. Now, the numerical techniques are making a useful design skill for the missile homing. A main theme of this paper is to study numerical simulation technology of EOCM for the dual-seeker that consists of a radar/infrared integrated and a evaluating method about the effectiveness for EOCM is discussed as well.
