Sentences with phrase «faint radio signals»

In observations with ALMA (Atacama Large Millimeter / submillimeter Array), a gigantic radio telescope which will be constructed at 5000 - meter altitude in Chile, this generation technique of millimeter / submillimeter wavelengths using the photonic technology will play an important role in detecting faint radio signals from the universe.
