A Study on the Effect of Building on the HF Direction Finding

Abstract

The effect of new building on the HF direction finding(DF) is analyzed. Commercially available software is used to get array manifold of the HF DF system. The terrain, building and the array antenna system are modelled. New building near the antenna system is also modelled to see whether it actually has an effect on the performance of the DF system. MUSIC and interferometer DF algorithms have been employed.
