- At the Defence Research Establishment of Sweden (FOA) an experimental S-band receiving digital array antenna for radar applications has been designed and built. It consists of a horizontal uniform linear array (ULA) of 12 antenna elements, whose digitized signals are processed in non-real time in a computer. Accurate calibration is utilized.We have compared several spectral and parametric direc- tion-of-arrival (DOA) estimation methods for varying DOA separations, number of samples and signal-to-noise ratios (SNR) on measured data from an anechoic cham- ber.At ideal conditions the resolution can be improved con- siderably with model based DOA methods compared to conventional beamforming. We achieved a resolution 1below /10 of the resolution of conventional beamforming.
