Method and apparatus for the directive direction finding

A directive direction finding apparatus, comprising:

• a directivity-enabled antenna array including a plurality of directional antennas, each having directivity in a same direction, the directivity-enabled antenna array being configured to spatially limit signal sources incident from the same direction in order to reduce interference and to enable direction finding with a relatively small number of receiver channels;
• an RF/IF receiver connected to the directivity-enabled antenna array;
• a digital receiver connected to the RF/IF receiver;
• a direction finder connected to the digital receiver;
• a directivity control unit configured to control an operation of the directivity-enabled antenna array;
• and
• a transport/control interface connected to the direction finder and to manage control and operation of the directivity-enabled antenna array, the RF/IF receiver, the digital receiver, the direction finder and the directivity control unit,
• wherein the directivity control unit includes a first buffer distributor disposed between a plurality of subarrays and a plurality of receivers, the first buffer distributor being connected to a plurality of single antennas and configured to convert analog signals to digital signals.
