Phase Only Synthesis of Antenna Patterns Using Iterative Restoration Methods
In this work, the method of iterative Fourier transform phase reconstruction, conventionally used in holography and optical image reconstruction, is applied to phase only synthesis of antenna patterns. The method is applied to two types of pattern synthesis problems: "main lobe beam shaping" and "side-lobe-level reduction". The proposed method is most useful in the efficient employment of attai...
متن کاملStream Restoration in the Upper Midwest, U.S.A
Restoration activities intended to improve the condition of streams and rivers are widespread throughout the Upper Midwest, U.S.A. As with other regions, however, little information exists regarding types of activities and their effectiveness. We developed a database of 1,345 stream restoration projects implemented from the years 1970 to 2004 for the states of Michigan, Ohio, and Wisconsin in o...
متن کاملOak Savanna Restoration: A Case Study
A degraded oak savanna in southwestern Wisconsin is being restored using intensive cutting of undesirable shrubsbuckthorn (Rhamnus cathartica), prickly ash (Zanthoxylum americanum), honeysuckle (Lonicera spp.)-and selective removal of trees that are crowding the open-grown bur (Quercus macrocar/Ja) and white (Q. alba) oaks. Land use records and historic aerial photographs have been used to guid...
متن کاملA Historical Perspective and Future Outlook on Landscape Scale Restoration in the Northwest Wisconsin Pine Barrens
The concurrent discussions of landscape scale restoration among restoration ecologists, and of historic disturbance pattern as a guideline for forest management among forest scientists, offer a unique opportunity for collaboration between these traditionally separated fields. The objective of this study was to review the environmental history, early restoration projects, and current plans to re...
متن کاملRehabilitation of a Blue Oak Restoration Project 1
Two remediations were tested for improving height growth and survival on a 2-yearold, failing, blue oak (Quercus douglasii) restoration project. Replanting acorns and seedlings with plastic treeshelters resulted in 75 and 88 percent survival, respectively, in areas previously showing almost total mortality. After 3 years, average height of replants (141 cm) exceeded the original planting (19 cm...
