AstroMesh可展开网状反射器支持Ku和Ka波段商业卫星任务的潜力进行了研究。工作的重点是预测反射器的增益/损耗为6米口径点设计工作在14 GHz和30 GHz。使用RMS表面误差从系统和随机源的增益/损耗估计通过Ruze被证明是准确的，和系统组件的栅瓣性能被证明是可以接受的。网格反射率性能和可行的Ku和Ka波段点设计的总损耗估计。
The potential for the AstroMesh deployable mesh reflectors to support Ku- and Ka-band commercial satellite missions is investigated. The focus of the work is on predicting reflector gain/loss for 6-meter aperture point designs operating at 14 GHz and 30 GHz. The use of RMS surface errors from both systematic and random sources for gain/loss estimates via Ruze is shown to be accurate, and grating lobe performance for the systematic components is shown to be acceptable. Mesh reflectivity performance is given and total loss estimates for viable Ku- and Ka-band point designs are presented.
