PROBLEM TO BE SOLVED: To provide a technique for dealing with the interference between multifrequency CW radars.SOLUTION: Interference determination means (30: S120 to S160) determines whether multifrequency continuous waves CW, as one type of radar waves, interfere with each other on the basis of a beat signal generated by mixing a transmitted signal and a received signal of the radar wave. If the interference determination means determines that interference occurs, selection means (30: S220) selects either an own device or a counterpart device that is an interference counterpart according to an interference occurrence situation. If the selection means selects the own device, frequency changing means (30: S230) changes a central frequency of the multifrequency CW transmitted from the own device. |
