Abstract
In the paper output signals of adaptive beamformer of a land-based AESA (Active Electronically Scanned Array) [14] surveillance radar were analysed for simulated air picture. Obtained results were compared with those achieved from classical beamforming technique used typically with little ambient interference, in fully customisable parameters of environment and simulated object. Received data was processed by a monopulse based angle estimator. Selected methods of adaptive beamforming techniques were analysed and classified by their ability to improve signal-tointerference ratio in a given scenario for ABT (Air-Breathing Threats) objects. Obtained results were confronted with expected deformations in main lobe of antenna directional pattern and their effect on accuracy of estimated angle. Object’s parameters calculated using adaptive beamforming techniques were compared with those received when no improvement of signal-to-interference ratio technique was used. The possibility of applying multiple (adaptive) monopulse ratio curves for multiple antenna patterns in manual, automatic or semi-automatic mode was investigated.
