| Popis: | Radio astronomical observations are increasingly corrupted by radio frequency interferences. Thus, real- time ltering algorithms are becoming essential. One approach is to use a speci c time property of the Telecoms signals : the cyclostationarity. This property can be exploited for detection purpose or ltering purpose. In par- ticular, new generations of radio telescopes will be based on antenna arrays providing the possibility of applying spatial ltering techniques. In this paper, we compare the performance between classical approaches based on power statistics and cyclic approaches. This comparison is done through simulations on synthetic data and through simulations on real data acquired with the new generation low frequency array radio telescope, LOFAR. |
