RECONFIGURABLE RADIO DIRECTION FINDER SYSTEM AND METHOD

The reconfigurable radio direction finder system (10) and method uses a reconfigurable antenna (26) to electronically cycle through a plurality of different antenna configurations. Specifically, the reconfigurable antenna (26) is cycled through N different antenna configurations, where each antenna configuration has a pointing direction associated therewith defined by an elevation angle Θ n of an n-th antenna configuration, where n is an integer between 1 and N, and an azimuthal angle Θ n of the n-th antenna configuration. A received signal strength of the radio signal is measured for each of the antenna configurations as a power output of the n-th antenna configuration, P n. A spherical weighted directional mean vector (X DF,Y DF,Z DF ) is then estimated for the radio signal as formula (I).
