Csi proposes to demonstrate the feasibility of high efficiencey multi-frequency antenna feed systems combining the high-efficiency advantages of near-field cassegrain techniques (dual-reflector shaping, low transmission line losses) with the multi-frequency and simplicity advantages of the coaxial… More

Explore the feasibility of an electronically controllable reflective lens to form the subreflector of a dual reflector antenna and compensate electrically for main reflector surface distortions. it could also provide limited but extremely rapid steering of the secondary beam of the antenna. such a… More

An innovative approach to forming a null in the secondary pattern of a reflector antenna is developed by this project. an electronically controllable reflective surface being developed on a nasa sbir is the starting point for the work. this project extends the performance of the surface so that it… More

From a control theory perspective, ballistic missile defense requires a distributed dynamic non-linear control system. The conventional approach to coordinating the allocation and use of components that are geographically dispersed and functionally diverse is through a central management function… More

Computer Science Innovations, Inc. (CSI) proposes to research and develop the Range Operations Data Extraction and Ontology (RODEO) System. RODEO encompasses an ontology for the space launch and range operations domain, an information extraction subsystem (IES) to identify relevant concepts in… More
