The definition and classification method of the radar power supply system are proposed for reliability analysis of the radar power supply system. The reliability models of the direct and the energy management power supply system architectures are built based on the reliability theory. The analytic expressions of basic reliability, mission reliability, MTBCF and MTBF for the power supply system architectures are derived, which provide the theoretical support and calculation method for reliability analysis of the radar power supply system architecture. It is proved that the MTBCF of the energy management architecture is greater than that of the direct architecture by the theoretical analysis. An engineering example shows that only the energy management architecture meets the requirements of the system reliability index. The effectiveness of the reliability analysis method proposed in this paper is verified. The classification of architecture and the calculation method of radar power supply system reliability presented in this paper provide a theoretical basis for the optimization of power supply system. It has great theoretical and engineering application value.
