随着光电技术的发展,激光近炸引信已经广泛应用于面空导弹、空空导弹等领域。针对大探测场激光近炸引信在国内外导弹中的实际应用,综合目标特性、目标探测、判别要求、以及工程实践经验,根据实验结果,重点分析了其常用的四种光束布局方式的特点和适用范围,给出了不同光束布局方式的分析、比较方法。研究成果已应用于实际设计中。 With the development of optoelectronic technology, laser near-fuze has been widely used in surface-to-air missiles, air-to-air missiles and other fields. According to the practical application of laser proximity fuze in large exploration field in domestic and overseas missiles, the target characteristics, target detection and discrimination requirements, as well as practical engineering experience are given. According to the experimental results, the characteristics of the four commonly used beam layout methods are analyzed. The scope of application, given the different beam distribution methods of analysis, comparison methods. The research results have been applied to the actual design.
