Radar device

A radar device comprising:

• a transmission radar which divides each of multiple frequency bands in such a manner that differences between center frequencies in respective frequency bands after division are equal, and transmits, in time division manner, transmission signals of which transmission frequencies are the center frequencies in respective frequency bands after division;
• a reception radar which receives each of reflection signals that are transmission signals transmitted in time division manner from the transmission radar and then reflected from a target, and converts each of the reflection signals into a reception video signal;
• a rearrangement processor which rearranges each of the reception video signals converted by the reception radar in such a manner that sets of the reception video signals corresponding to the multiple frequency bands before being divided by the transmission radar are arranged in a row;
• a band synthesis processor which performs a band synthesis on each of the reception video signals rearranged by the rearrangement processor;
• and
• a target detector which detects a range to the target from the reception video signals subjected to the band synthesis by the band synthesis processor.
