In space environment, large deployable space truss antenna is affected inevitably by shadowing effect of the earth. In addition, it is also affected by shadowing effect of itself (including the shadow of reflector mesh and members). A 5-m diameter large deployable cutting-parabolic antenna model is designed. It is composed of a supported backbone (deployable truss) and a reflector surface (flexible mesh). According to the spatial position of every member and orientation between members and the sun, a new method is proposed to compute the shadowing factor of all members of the space antenna structure. It's proved that this method is simple and effective.
