OTH Performance Trade-Off Analysis.
Abstract
The objective of the OTH Performance Trade-Off Analysis Program is to perform cost/performance trade-off analysis on the use of multiple antenna/receiver phased arrays for OTH backscatter radar systems. This study considers generally the comparison of conventional HF radar designs using multiple antenna elements and analog beamforming devices with advanced designs using multiple antennas, multiple receivers and digital beamforming. These advanced digital designs include Fast Fourier Transform azimuth processing which efficiently forms a large number of antenna beams, adaptive azimuth processing which tailors the antenna pattern to optimize the output signal-to-noise (plus interference) ratio in the existing noise-interference environment and the use of thinned arrays to realize cost reductions.
