The radar software system safety assessment indicators are mostly qualitative indicators, and the coupling, randomness and ambiguity are strong. Aiming at the problem of radar software system safety assessment, this paper proposes a method based on entropy weight method and cloud model theory assessment. Firstly, the entropy weight method is used to determine the index weight, and then the cloud model theory is used to combine the index weight with the cloud model to obtain a comprehensive cloud. Finally, the comprehensive cloud is compared with the standard clouds to obtain the safety assessment results of the software system. The feasibility and scientificity of the method are proved by comparison with other assessment methods.
