Abstract

A first radar transmitter and a second radar transmitter transmit a first modulation signal and a second modulation signal which are generated by repeating a predetermined time of code sequences, each of which has a predetermined code length, using a first code width and a second code width, respectively. An A/D converter converts the modulation signal into a discrete signal in a sampling cycle shorter than a difference between the first code width and the second code width. A positioning section separates a plurality of reception signals using a first correlation value based on outputs from the A/D converter and a first delay section corresponding to the first code width and a second correlation value based on outputs from the A/D converter and a second delay section corresponding to the second code width.
