摘要： A method for determining whether a target is within a direction sector of interest of a direction finder and a device for carrying out the method are disclosed. The method calls for (a) predefining the sector of interest; (b) providing at least two antennas; (c) generating an in-phase reference pattern, and establishing wireless communication between the direction finder and the target; (d) attenuating the wireless communication signal between the direction finder and the target and recording the attenuation value which corresponds to the loss of wireless communication as the R reference value; (e) generating an out-of-phase null pattern, and re-establishing wireless communication between the direction finder and the target; (f) repeat step (d) except this time recording the attenuation value which corresponds to the loss of wireless communication as the N null value; (g) determining whether the difference R−N is above or below the threshold difference.
