<p><P>PROBLEM TO BE SOLVED: To provide a radar device improving an SN ratio of a reception signal reflected from a target, wherein an amplitude temporally largely changes, and wherein a period of a large amplitude is short, so as to allow improvement of target detection performance. <P>SOLUTION: This radar device has: a receiver 4 converting, into a digital video signal, the reception signal obtained by receiving a reflected wave of a transmission wave transmitted into a space; an unnecessary wave suppression device 9 suppressing an unnecessary wave component from the digital video signal; a convolution computing device 10 performing convolution computing with an reference signal becoming a complex conjugate in each pulse of the reception signal from a target that is a detection target, and having length in a pulse direction capable of maximizing integration gain, to the signal wherein the unnecessary wave component is suppressed; and a detector 8 detecting a signal of the reflected wave from the target on the basis of a signal outputted from the convolution computing device 10. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
