摘要
针对平流层飞艇载有源雷达辐射功率大、能源供给受限、难以全天时工作问题,提出了一种有源无源一体化雷达系统设计方案.该系统基于圆阵天线的外辐射源雷达可与综合脉冲孔径雷达共用天线、馈线、接收、信号处理等设备,只需融合外辐射源雷达信号处理软件及配置资源即可,不需要额外增加硬件.仿真分析表明,通过有源无源一体化雷达设计,不仅拓展了系统工作模式,而且还改善了系统可用度,提高了系统探测效能.
Stratospheric airship-borne active radar has the problems of large radiation power,limited energy supply and difficulty working all day.In order to solve the problems,this paper proposes a design scheme for active-passive integrated radar system.The proposed system based on passive radar with circular array antenna can share antenna,feeder,reception,signal processing and other equipment with synthetic impulse and aperture radar(SIAR).It only needs to integrate the signal processing software and configuration resources of the passive radar,without the need to add any other hardware.Simulation analysis shows that the active-passive integrated radar design not only expands the working mode of the system,but also improves the system availability and enhances the detection efficiency of the system.
