Abstract

Radio astronomical observations are increasingly contaminated by man-made communication signals. TDMA signals such as GSM can be suppressed in the time domain by inhibiting the correlation process when the interfering signal is present. In this paper we propose a spectral-temporal detection and blanking scheme applicable to array radiotelescopes. The effectiveness is demonstrated through simulations as well as theoretical analysis
