Abstract :
The additional estimation error introduced by the use of finite ground planes is evaluated numerically for two types of conventional direction finding (DF) systems. The analysis reveals that commonly accepted ground plane dimensions result in degraded estimation accuracy when the incoming signals are of unknown polarization.
