摘要
信号情报侦察卫星用于侦收地面雷达、通信和测控等系统所辐射的电磁信号并对其定位,是航天侦察的重要手段。介绍了信号情报侦察卫星的使命和分类,通过对星载侦察接收设备的组成、主要性能要求和特点的分析,对大型天线及在轨展开技术,宽频段、高灵敏度、大动态范围的一体化信道技术,星上信号处理技术和空间环境适应性等星载侦察接收关键技术进行了讨论,并展望了其发展趋势。
SIGINT（Signal Intelligence） satellite is used to detect, intercept and locate electromagnetic（EM） signals radiated by systems such as ground radar, communication and TT＆C systems. It is an important means for space reconnaissance. The missions and classification of SIGINT satellites are introduced. The components, main specifications and features are analysed. The key signal interception and receiving technology is discussed, including large antenna and its deployment technology, integrated channel with wideband, high sensitivity and large dynamic range, onboard signal processing technology and space environment adaptability, etc. Finally the development trend is expected.
