Abstract

This report summarizes four years studies of technologies for digital array antennas (DGA) at FOI. The studies Digital Array Antenna and later Array Antenna Technology started in 1998 as a continuation of the earlier program Antenna Integrated Microwave Technology (AIMT) that was carried out in cooperation between then FOA and Ericsson Microwave Systems AB (EMW). The AIMT program gave as a result an experimental digital array antenna at S-band. Digital array antenna technology and the experimental array antenna have been studied and developed further for use in radar measurements and technology evaluations. Array antenna technology for millimetre waves has also been studied and developed. The DGA program has developed the digital array antenna technology for new concepts in radar networks and command and control systems. Different methods for control, fusion and optimisation have been developed for digital array antenna radar systems. Measurements with the experimental digital array antenna have given new insights into digital beamforming for different functions. Developments of array antenna technologies and microwave MMIC modules have given new experiences in design of digital array antennas. Different types of circuit design have been studied to develop digital array antennas.
