<p><P>PROBLEM TO BE SOLVED: To output all frequency components, while suppressing increase of a circuit scale, in a coherent integration having a large number of integration sweeps, in a radar device for integrating a received signal. <P>SOLUTION: This radar device includes a data input part 10, a first butterfly circuit 20, a first selector circuit 30, a second butterfly circuit 40 and a data output part 50. An integration circuit is separated by a selector circuit into a first half and a latter half of butterfly operation (first and second butterfly circuits). A frequency component to be outputted is selected according to a selection position of the selector circuit. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
