For the shortage of the system reliability datum in the initial stage of the design of a spaceborne antenna deployment mechanism, unascertained method for system reliability allocation is proposed. This method is based on the weighted allocation method. Through introducing the unascertained information into the matrix of weight coefficients, the unascertained model for the reliability allocation of a spaceborne antenna deployment mechanism is built. By means of the arithmetic operation rules of unascertained rational number, the expression of unascertained weighting coefficient is derived. Finally, the reliability allocation of a spaceborne antenna deployment mechanism is given as an example. The possible reliability values and faith degrees of the system are obtained. The rationality and validity of the presented method are demonstrated.
