Abstract:

The primary task was to modify an existing HF phased array facility in Hudson, Colorado so that data could be collected on a large two-dimensional array in a format suitable for use for adaptive processing. The principal modifications included the construction of a 32 element cross array of vertical monopoles and the addition of quadrature outputs to the existing 32-channel receiver and data acquisition system. Additional tasks included the development of software for controlling the data collection system, for processing and displaying the field data, for producing simulated field tapes for specific array geometries and model environments, data collection under a variety of conditions, and analysis numerical simulations to guide the design of the antenna array and data reduction to evaluate the performance improvement obtained through adaptive processing.
