<P>PROBLEM TO BE SOLVED: To provide a radar device for performing stable correlative tracking. <P>SOLUTION: A radar device includes: a transmitter/receiver 20 for repetitively transmitting/receiving down sweep or up sweep signals of an FMCW system; a beat frequency axis conversion part 36 for performing coordinate conversion into fbx-fby axes which express a beat frequency space by using a measurement angle value based on the signals from the transmitter/receiver; a correlative tracking part 37 for performing correlative tracking through the use of a position, a speed, and an acceleration in the space of the fbx-fby axes obtained by conversion in the beat frequency axis conversion part; and an X-Y axis conversion part 38 for converting a result obtained by the correlative tracking in the correlative tracking part into the position and speed of the X-Y axes. <P>COPYRIGHT: (C)2012,JPO&INPIT |
