在对激光对抗装备的外场试验鉴定中，需要考虑提供近似实战条件的激光信号环境，本文从实际需求入手，阐述激光信号环境模拟系统的必要性，并结合外场试验需求，设想了激光信号环境模拟系统。 In the field experiment and appraisal of the laser countermeasure equipment, we need to consider the laser signal environment which provides the approximate actual combat conditions. Starting from the actual demand, this article elaborates the necessity of the laser signal environment simulation system. Combined with the field test requirements, system.
