激光作为一种主动式对抗技术，将会在光电对抗中发挥日趋重要的作用，它可干扰、致盲甚至破坏敌方侦察、制导、火控、导航及C3I系统中的光电设备，并可损伤、致盲人眼，因此激光武器是现代海战中重要的光电对抗武器。本文将对激光有源干扰技术进行初步探析。 Laser, as an active countermeasure, will play an increasingly important role in optoelectronic countermeasures. It can disrupt, blind and even destroy enemy reconnaissance, guidance, fire control, navigation and optoelectronic devices in C3I systems and can damage , Blind eyes, so the laser weapon is an important modern naval battle photoelectronic weapons. This article will be laser active interference technology for a preliminary analysis.
