Evaluation of Two Dimensional Adaptive Antenna Arrays
Abstract
The objective of the research reported here is to evaluate the improvement in HF antenna array performance achievable through adaptive processing under actual field conditions, emphasizing two dimensional array geometries. The approach has been to collect experimental data under a variety of propagation conditions and evaluate the performance of the array with and without adaptive beamforming. A two-dimensional HF phased array facility had been established at Hudson, Colorado in connection with other ARPA programs and this facility was modified for adaptive data taking. The modification included the construction of 32 modular receivers and a 32 element cross array of vertical monopoles. Data were recorded on digital tape and processed off-line to produce sky maps (signal strength versus azimuth and elevation) in the full bandwidth of the receivers (17kHz).
