微纳卫星组网电子侦察定位关键技术探讨

Key techniques of electronic reconnaissance and location based on micro/nano satellite network

基于微纳卫星的电子侦察还处于起步阶段,许多问题亟需解决。讨论了微纳卫星组网电子侦察定位三个方面的若干关键技术,分别是电子侦察基本架构、载荷硬件架构和星间组网通信。在提出松耦合和紧耦合组网侦察定位架构的基础上,讨论了对地面和空中动目标的定位方法以及载荷实现相关的关键技术,给出了一种星间链路方案,提出了一种基于参数的中频数据压缩方法,可为微纳卫星电子侦察技术的发展提供一些参考。

Electronic reconnaissance based on micro/nano satellite network is under research, and many problems need to be resolved. The key techniques of three aspects are discussed, including basic reconnaissance system structure, payload hardware structure and inter-satellite networked communication. By introducing loosely coupled architecture and tightly coupled architecture of networked reconnaissance, some key techniques of locating scheme of ground target and air moving target and payload implementation are analyzed. A method of inter-satellite link is proposed. A data compression technique for IF data is introduced based on parameterized method. This study can be referred by micro/nano satellite reconnaissance system.
