Design of a HF compact direction finding system based on colocated antennas

This paper deals with HF direction finding and antenna processing. Its main purpose is to present possibilities of using space, polarization and antenna diversity to determine DOA (direction of arrival) estimations with a colocated sensor. A high-resolution algorithm (MUSIC) is used to find the angles of arrival. Some experimental results obtained with a circular array and a colocated antennas sensor are presented.
