System and method for determining the relative direction of an RF transmitter

A method to determine a relative direction of a target RF transmitter, performed by a direction finding (DF) system comprising a central unit having a processing modue, and at least a pair of antennas having an electromagnetic-absorbing material between them, the method comprising:

• a) conducting wireless communication in which the target RF transmitter transmits wireless signals received at each one of the antennas of the DF system;
• b) measuring the signal strength of the target RF transmitter received at each antenna;
• c) calculating the difference between the signal strength measured at each one of the antennas in the pair;
• d) determining a relative direction of the target RF transmitter to be is the direction of the antenna within the pair of antennas in which the stronger signal was measured.
