Abstract :
A heterogeneous array is made up of sensors which are different from one another. It has been demonstrated that this original structure induces a polarisation sensitivity of the array and consequently, an improvement of the angular resolution in HF direction finding applications. This paper investigates the particular case of circular arrays set up with vertical active loop antennas.
