CCD成像制导武器在军事上的广泛应用,促使与之相应的光电干扰技术得以迅速发展,采用低能激光进行压制性干扰是一种有效的干扰方式。在实战环境中,难以保证激光束始终直射导引头内CCD探测器表面。为了验证视场外激光能否干扰CCD成像探测系统和干扰程度,首先介绍软破坏的实用性和可行性,进行了视场内、视场外激光干扰VC-210B型CCD探测器的实验,分析了视场外激光干扰的原理,并对激光软破坏某型CCD成像探测器所需能量进行估算,且从点源透过率角度说明激光视场外干扰的可行性。实验结果表明:视场外激光可实现对CCD成像探测系统的有效干扰。
The wide application of CCD imaging guidance weapons in the military has prompted the corresponding photoelectric interference technology to develop rapidly. The use of low-energy laser for suppressing interference is an effective interference method. In actual combat environment, it is difficult to ensure that the laser beam always directs the CCD detector surface in the seeker. In order to verify whether the field-of-field laser can interfere with the CCD imaging detection system and the degree of interference, the practicality and feasibility of soft damage are introduced firstly. The experiment and analysis of VC-210B CCD detector with field and field laser interference The principle of field-of-field laser interference is also discussed. The energy required for soft-destroying a CCD imaging detector is estimated, and the feasibility of laser field interference is illustrated from point source transmittance. The experimental results show that the out-of-field laser can effectively interfere with the CCD imaging detection system.
