 | The objectives of this project began with the construction and deployment of two and later three multifrequency HF radar instruments (called MCR for Multifrequency Coastal Radar) to Monterey Bay, California. Further experiment deployments were to the Virginia coast and to Lake Michigan for fresh water experiments (NSF sponsorship). The data collected at these sites is reduced, analyzed and interpreted to achieve the specific research objectives listed below: 1. Improvement of ... |

| The Innovative Coastal-Ocean Observing Network (ICON) is a partnership of government, academic, and industrial entities funded by the National Ocean Partnership Program (NOPP). Its goal is to bring together modern measurement technologies, to develop new technologies, and to integrate them within a data assimilating coastal ocean circulation model. The major components of the observing network include: (1) surface current maps from shore-based high frequency (HF) radar installations; (2) subsurface currents, ... |

|
| Digital beam synthesis using a high capability opto-electronic radar (HICAPOR) by Alvin M. Despain and John F. Vesecky. This JASON study investigates the capabilities of HICAPOR by calculating the antenna beam patterns formed by typical implementations of this concept. A wide variety of parameter choices are investigated and antenna patterns for HICAPOR are compared with conventional phased array and true time delay techniques of beam formation. The presentation begins with ... |

| Sea ice is of fundamental importance in weather, climate and other geophysical processes. It is also an important factor for naval operations in the polar regions, in particular regarding transport of personnel and material in regions where sea ice is likely to be found and assessment and prediction of acoustic environments in polar regions. Ridges (and keels) in sea ice are important because they provide a rougher surface and thus ... |

|
| HF surface wave radar for ocean wave and current measurements began with collaborative work at Stanford University and Scripps Institution of Oceanography in the late 1960's. Two of the participants in this project (Drs. Teague and Vesecky) have worked with HF radar observations of the ocean since these early experiments. Under this grant a new HF radar design was begun and some prototype construction completed. This work led to construction ... |

| Sea ice is of fundamental importance in weather, climate and other geophysical processes. It is also an important factor for naval operations in the polar regions, in particular regarding transport of personnel and material in regions where sea ice is likely to be found and assessment and prediction of acoustic environments in polar regions. Because sea ice has a large geographic extent and short time scale for variability synthetic aperture ... |

|
 | The overall objective of this research is to revisit the slowly varying or S component of solar microwave emission having in hand a much more detailed knowledge of active region structure than was available when the S component was studied extensively in the 1950s and 1960s. In particular we want to consider the radio emission from the active region loop structures so evident in Skylab X-ray and UV images. (Author) ... |

|
| A workshop on magnetospheric wave-particle interaction sponsored by ARPA and ONR was held at Stanford Research Institute, Menlo Park, California on 11-13 July, 1972. The general view of the workshop participants was that significant wave amplification at ULF and VLF frequencies can be artificially stimulated by injecting cold plasma outside the plasmapause in the magnetosphere, and that specific military applications for such wave amplification (communications) and its assoicated particle precipitation ... |
