<p><P>PROBLEM TO BE SOLVED: To provide an antenna device for a radar in which a multiple radar system composed of a plurality of antennas which can be flexibly arranged can be constructed, which is reduced in size and weight, and can be adapted to each antenna eve if a failure occurs. <P>SOLUTION: The antenna device for the radar includes: an ACDC converter 11 for converting an AC voltage from an AC voltage supply 1 into a DC voltage and supplying the DC voltage; and the plurality of antennas 14, 15 and 16 each generating a pulse current on the basis of the DC voltage and transmitting and receiving a pulsing high-frequency signal. The ACDC converter 11 includes a plurality of switch circuits 4a, 4b and 4c for distributing electric power to the plurality of antennas. Each of the plurality of antennas includes: a plurality of RF modules 13 for controlling the operation of the transmission and the reception of the pulsing high-frequency signal; and a plurality of DCDC converters 12 which are disposed so as to correspond to the plurality of RF modules 13 connected to the RF modules 13 at respective one-side ends, and connected to one of the plurality of switch circuits 4a, 4b and 4c at respective other ends. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
