Abstract:
1. A method for radar target detection comprising the steps: providing an antenna comprising a plurality of antenna elements arranged on the exterior circumference of a plurality of platters, and a plurality of amplitude/phase modules, wherein each of said plurality of amplitude/phase modules is coupled to at least two antenna elements; selecting a first subset of said plurality of antenna elements; receiving a signal at said antenna; using an azimuth beamformer to calculate a sum (Σ) azimuth beam and a delta (Δ) azimuth beam for each amplitude/phase module which is coupled to an antenna element in said selected first subset and to combine each sum (Σ) azimuth beam and a delta (Δ) azimuth beam from every amplitude/phase module on each platter into a single sum (Σ) azimuth beam and a single delta (Δ) azimuth beam for that platter; and using an elevation beamformer to form an elevation beam.
