PRAGUE, April 2 (Xinhua) -- U.S. missile defense experts, who arrived in the Czech Republic on Monday, will analyze the electromagnetic waves present at the possible site of the U.S. radar base that may be constructed in the country, Czech Defense Ministry spokesman Andrej Cirtek said.

    The collected data will be used for drafting a comprehensive spectral analysis of the possible radar locality, which is to be based in the Brdy military grounds southwest of Prague, the capital of the Czech republic.

    "There is only a low possibility that the operation of the radar system would seriously interfere into the functioning of any local facility," Cirtek said.

    The five-member U.S. team met representatives of the Czech military. They will remain in the country until Friday.

    The Czech government officially agreed to start negotiations with the United States over the location of a radar base, which is part of a planned U.S. anti-missile shield in central Europe, on Wednesday. The negotiations are expected to last until the year's end.

    The United States unveiled its plan in January to place a radar system in the Czech Republic and 10 interceptor missiles in Poland, as components of the missile shield. Washington has insisted that the system is designed to counter future threats from countries such as Iran.

    However, most Czechs oppose the proposed radar base, citing fears over worsened relations with Russia and a threat to national security and local environment.
