Research on Cognitive Satellite in Complex Environment Based on Dynamic Electromagnetic Spectrum Management

Compared with the space systems abroad, it is hard for domestic spacecraft to meet the increasingly high demand in future information war, especially in providing a complex environment awareness, avoiding the enemy jamming and deception and improving the anti-interference ability of the system as a whole. Based on the analysis of the existing problems on the basis of spatial information system construction, this paper integrates cognitive technology into the traditional space system, puts forward new concept cognitive satellite which has the function of dynamic perception, presents the cyclic process of the cognitive satellite. On the basis of the above, this paper proposes the architecture principles of the cognitive satellite and prospects the application study of the cognitive satellite. Developing the cognitive satellite can enhance our country’s advantages of system development and engineering application in the future, and the theory research can be in the position of the fundamental equilibrium compared with the developed countries in the new stage of space system development.
