<p><P>PROBLEM TO BE SOLVED: To provide a radar device with which a target blind speed region generated by MTI to perform a clutter restriction process is reduced by radio wave transmission. <P>SOLUTION: A transmitter 3 sequentially switches transmission frequency of a pulse signal to f<SB>1</SB>-f<SB>3</SB>in time division manner. Reflection waves of radio waves emitted at each transmission frequency are received by an antenna 1 and then phase-detected by a receiver 5 to be a reception processed signal. A frequency selection means 8 performs peak detection or threshold detection processing to each of output signals of an MTI processing means 7 at the transmission frequencies f<SB>1</SB>-f<SB>3</SB>to detect a target. The frequency selection means 8 selects a reception processed signal including a target signal among the plurality of reception processed signals as a measurement object signal. Based on the measurement object signal from the frequency selection means 8, target detection processing and distance measurement processing are performed, and the distance to a target is measured. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
