用于目标指示器的激光器研究进展
|
摘要
激光半主动制导技术极大地提高了导弹命中率,激光器作为目标指示器的核心器件,其研究进展对整个激光制导武器系统意义重大。首先介绍了用于目标指示器的激光器的发展历程和研究现状;然后阐述了当前该激光器的主要技术原理和方案,分析了其优势和不足;最后对该激光器的未来发展方向进行了展望。
Semi-active laser guidance technique greatly improves the hits rate of munitions.The development of laser device,as the core part of laser target designators,is highly significant for the entire weapon system.Development and current status of laser device used for laser target designators is sketched.Current major technical principles and schemes are introduced subsequently,along with the pros and cons of the schemes.Finally,the laser device′s future outlook is provided.
