<p><P>PROBLEM TO BE SOLVED: To improve a sensing processing speed of a radar sensing an object of a specific area. <P>SOLUTION: The FM-CW system radar comprises at least a radar receiving part 201 for generating a beat signal by receiving a reflection wave reflected on the object; a filter part 202 for removing a signal except for a sensing area 103 from the beat signal; an A/D conversion part 203 for digitizing the filter-processed beat signal; an FFT processing part 204 for performing FFT processing to the digitized beat signal; and a vehicle detection part 205 for detecting a distance, a relative speed and the like of the object from the FFT data. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
