Abstract: A multi-objective optimization strategy for composite airborne radome is proposed. In order to meet the requirements of the radome's transmission coefficient, based on the transmission line theory, the radome electrical performance is analyzed to find the layer thickness interval that meets the electrical performance, and the transmission coefficient constraint is converted to the design variable layer thickness. Under the condition of satisfying the electrical performance of the radome, an optimized mathematical model with the minimum mass as the target, the structural stiffness strength as the constraint and the different thickness of the cover wall as the design variables is established to realize the lightweight design of the radome. The optimization analysis is carried out with an A-sandwich airborne radome as an example. The results show that the optimized radome has significant lightweight effect and high transmission coefficient performance, which proves the feasibility of the method.
