Instrument concept of NEXRAD In Space (NIS) - a geostationary radar for hurricane studies

The current Geostationary Operational Environmental Satellites (GOES) are eqipped to make cloud top measurements only. In contrast, a millimeter-wave radar allows 3-D measurements of precipitation associated with hurricanes and other convective systems. It also provides important inputs for numerical weather prediction models for improving the accuracy of weather nowcasting and forecasting.

Thermal distortion analyses of a three-meter inflatable reflectarray antenna

Gossamer space structures are relatively large, flimsy, and lightweight. As a result, they are more easily affected or degraded by space thermal environments compared to other space structures. This study examines the structural integrity of a three-meeter Ka-band inltable/self-rigidizable reflectarray antenna under space thermal environments.

Deployment study of a self-rigidizable inflatable boom

Deployment dynamic behavior of an inflatable space structure is analyzed using a combination of gas dynamic analysis and rigid body kinematics simulations. Modeling technique is presented for deployment of a simple cantilever boom that is rolled up on a cylindrical mandrel.

Development of a three-meter Ka-band reflectarray antenna

With the development of inflatable technologies, inflatable structures used as large space antennas are becoming very possible for near term space missions. This paper discusses the development of an inflatable/self-rigidizable structure for a three-meter Ka-band reflectarray antenna.
