An azimuthal omni-directional array for multi-target acquisition and tracking

A technique for multi-target acquisition and tracking is presented. The target localization technique requires only the amplitude signal of each antenna, and not the phase. The proposed design can operate over a wide frequency range (20-100 GHz). The array can resolve a large number of targets accurately and is lightweight and relatively small (2 ft in diameter or less). The array has no moving parts, and no expensive RF electronics such as phase shifters and power combiners are needed. The design can be extended to hemispherical arrays for omni-directional half-plane coverage.<>
