【摘要】 导弹预警卫星是空间预警系统的重要组成部分。以美国为例,介绍了DSP、SBIRS和Next-Gen OPIR三代天基红外导弹预警技术的发展,重点分析了天基红外系统中红外光学载荷的工作体制、性能参数及技术特点。同时,分析了天基红外预警系统的工作模式,提出高低轨卫星组网、多波段/长线列/大面阵探测、构建弹性体系等是天基导弹预警技术的发展趋势。更多还原

【Abstract】 Missile warning satellite is an important part of space warning system. The development of space-based infrared missile warning technology of America such as defense support plan(DSP), space-based infrared satellite(SBIRS) and next generation overhead persistent infrared program(Next-Gen OPIR) is introduced. The operation system, performance parameters and technology characteristics of mid-infrared optical load in space-based infrared system are analyzed. And the operation mode of the space-based infrared warning system is analyzed. The development trend of space-based missile warning technology such as high and low orbit satellite networking, multi-band, long line array, large format detection and elastic system construction is proposed.更多还原
