| 摘要 |
The present invention relates to a method for determining the direction to a target by a direction finder, which comprises: predefining a direction axis as a 0° direction; first and second pair of antennas arranged such that a first line connecting between the first pair of antennae defines a 0°-180° axis parallel to said direction axis, and a second line connecting said second pair of antennas defines a 90°-270° axis perpendicular to said direction axis; generating a 0° antenna pattern and establishing a wireless communication between the direction finder and said target; attenuating the wireless communication signal until lost and recording the attenuation value; generating a 180° antenna pattern using said first pair of antennas, and establishing a wireless communication between the direction finder and said target; attenuating the wireless communication signal until lost, and recording the attenuation value and concluding a true direction to the target.
