Abstract

The purpose of the work is to develop testing and calibration technique of large phased antenna arrays using reference noise generator as a standard signal source. This technique is developed for calibration of the phased antenna array of the unique decameter wave radio telescope UTR-2, but they could be easy adapted for similar large arrays with analog and digital beam forming.
