Pencil Beam Array Development
Abstract
During FY89 through FY94 we designed and partially constructed a transmit/receive array for imaging the ocean near-surface zone. During FY92-93, a proof-of-concept prototype with reduced numbers of transmit and receive elements was designed, fabricated and tested. Tests were conducted in local waters using a simple, fixed mooring. The final design of the array allowed for pan and tilt, and incorporated features for self-calibration and accurate position measurement. With this array surface, volume, bottom and ice-scattering experiments in both monostatic and bitatic arrangements would have been possible in future measurements. Deployment of the Pencil Beam array system in specific experiments was considered. Funding for this project was terminated in FY93, and work in FY93/94 was focused on the Cascadia Basin Experiment, CABEX. Hardware developed for this Pencil Beam project was used in that experiment.
