Abstract
A radio direction-finding system with at least two loop antennas, generating a reference signal, wherein the radio direction finding system has more than one dipole distributed around, and parallel to the mast which sum the signals output by the various dipoles, the resulting sum signal being used as the reference signal.
Claims9
A radio direction-finding comprising:
- at least two loop antennas on a mast, said antennas extending in planes parallel to said mast;
- a plurality of dipoles distributed around said mast and parallel thereto;
- first processing means for summing the signals output by the plurality of dipoles, the resulting sum signal being used as a reference signal for radio direction finding processing:
- and
- second processing means for performing a radio direction finding processing on the signals received by the various antennas.
