Evaluation of angle of arrival estimators using real multipath data

摘要: This paper presents the results of a performance evaluation that were made on two angle target arrival estimation schemes are suitable for use in low-angle tracking radar environment. The were: (1) A maximum likelihood receiver, and (2) an adaptive cancellation scheme supplied with calibration curve. also describes sampled aperture facility has been developed at Communications Research Centre (Ottawa) multipath studies. was used to obtain data evaluating these estimators. show that, under right conditions, both processors capable resolving equal small fraction beamwidth, using one snapshot array data. scheme, consistently, slightly better than receiver.
