摘要
多模复合制导技术在现代精确制导武器系统中扮演着重要角色.为提升制导性能,有必要开展半实物复合仿真试验研究制导系统的性能和功能.波束合成器作为复合制导半实物仿真系统的关键部件,通过反射红外信号、透射射频信号实现红外/射频信号复合,并将其通过共口径投射到被测设备入瞳处.文章设计薄膜式红外/射频波束合成器,并进行性能分析,结果表明薄膜式红外/射频波束合成器红外(中、长波)反射率不低于90%,射频(S、C、X、Ku、Ka、W波段)透过率不低于97%.
Abstract
Multi mode composite guidance technology plays an important role in modern precision guided weapon systems.In order to improve guidance performance,it is necessary to conduct semi physical composite simulation tests to study the performance and function of the guidance system.As a key component of composite guidance semi physical simulation system,the beam combiner reflects infrared signals and projects radio frequency signals to achieve infrared/radio frequency signal composite,and projects them to the pupil of the tested device through a common aperture.In this paper,the thin-film infrared/RF beam synthesizer is designed and its performance is analyzed.The results show that the infrared(medium and long wave)reflectivity of the thin film infrared/radio frequency beam combiner is not less than 90%,and the radio frequency(S、C、X、Ku、Ka、W bands)transmittance is not less than 97%.
