Abstract
LOFAR (Low Frequency ARray) is a large new radio telescope aimed at unusually low frequencies under development at ASTRON. Using phased array technology, one of the instrumental components of this system is the beamformer using phase shifters. The use of phase shifters over physical time delay devices reduces cost of the system and increases flexibility. Phase shifters allow us to create multiple beams at hardly any extra cost and it opens the possibility of adaptive responses to interfering signals. The unusual frequencies, combined with the desire to use non regular array configurations for the system means that analytical analysis of the station beaxnformer is hard, if not impossible. We therefore introduce a numerical analysis of the station beamformer using simulations of the LOFAR station both in Matlab and in C++.
