1. Switched lobe (SL)

Simplest technique, also called switched beam.

Comprises of only a basic switching function between separate directive antennas or predefined beams of an array. The setting that gives the best performance is chosen.

2. Dynamically phased array (PA)

A direction of arrival (DOA) algorithm is included for the signal received from the user.

Continuous tracking can be achieved.

Generalization of the switched lobe concept.

3. Adaptive array (AA)

A DOA algorithm for determining the direction toward interference sources (e.g., other users) is added.

The radiation pattern can then be adjusted to null out the interferes
