Development Status and Trends of Space Reconnaissance in the US Military

Space reconnaissance has become an important part of modernized combat system, and is the key to obtaining the information dominance in advanced technology warfare and then mastering the initiative on the battlefield. Taking the US military space reconnaissance system as an instance, this paper combs the development status from four aspects: space optical imaging reconnaissance system, space radar imaging reconnaissance system, stationary orbit space signal reconnaissance system and variable orbit space signal reconnaissance system. Combining with the application examples of the US military, it analyzes the technology utilization from the central network, peacetime-to-wartime transformation, joint spying and preliminary reconnaissance, and it summarizes the US military space reconnaissance technologies from four aspects: the collaborative technology of heterogeneous reconnaissance network, high-speed transmission technology of intelligence data, high-resolution penetrating imaging technology, high-precision target positioning technology. Finally, this paper analyzes the development trend of space reconnaissance from five aspects: the mi-niaturization of space reconnaissance satellites, integration of reconnaissance networks, anti-jamming and anti-destruction of reconnaissance systems, integration sharing of reconnaissance information and intelligentization of information analysis and decision making, so as to provide references for the construction, application and development of future space reconnaissance systems.
