为了分析高能激光对成像制导系统的干扰效果,从制导武器的红外辐射强度出发,介绍了成像制导干扰效果评估的两种基本方法。以对比度评估方法为例,模拟了不同干扰强度、不同干扰质心激光干扰条件下成像制导系统的跟踪效果。结果表明对成像型制导系统实施有效激光干扰的手段主要有两个:一是增加激光干扰源的激光功率;二是激光干扰质心要尽可能地远离目标质心。
In order to analyze the interference effect of high-energy laser on imaging guidance system, two basic methods of imaging guidance jamming effect evaluation are introduced based on the infrared radiation intensity of guided weapons. Taking the contrast evaluation method as an example, the tracking performance of the imaging guidance system under different interference intensity and different interference center of mass laser interference was simulated. The results show that there are mainly two ways to implement effective laser jamming in imaging guidance system: one is to increase the laser power of the laser interfering source; the other is that the laser interfering center of mass should be as far as possible away from the target center of mass.
