 | This project involved the procurement and installation of enhancements to Michigan Technological University's Molecular Beam Epitaxy (MBE) facility. MBE is a thin film deposition technique that permits precise control of multiple element fluxes to a surface, permitting alloy layers as thin as one monolayer to be prepared under carefully controlled conditions of vacuum and temperature. Unlike most other thin film preparation techniques, the deposition conditions for MBE can be far ... |

| We investigated approaches for gathering information about a missile at long ranges employing flood-illumination by a laser and pupil-plane arrays of detectors. We catalogued target parameters that could be characterized with these measurements. We showed the ability to estimate the length, width, and orientation of the missile from pupil-plane speckle patterns. We demonstrated shape reconstruction from the autocorrelation function and improvements in those results by using a sidelobe-reduction algorithm. We ... |

 | The government conducts about 90 percent of its operations below 3.1 gigahertz, but only has exclusive use of 17 percent of the spectrum and shares 16 percent of the spectrum, while the private sector has exclusive use of 67 percent of the spectrum below 3.1 gigahertz. Title VI of the Omnibus Budget Reconciliation Act of 1993 requires the federal government to provide a span of radio frequencies totaling not less ... |

|
| During the past several years, the Congress has been critical of DOD'S management of military satellite communications-a primary concern being high costs. Congressional reports in 1989 and 1990 directed DOD to prepare a comprehensive, affordable architecture that defined all satellite communication requirements and potential solutions to satisfy the requirements. In November 1991, DOD published its military satellite communications architecture study that identified several alternatives for satisfying requirements, including the use ... |
