PROBLEM TO BE SOLVED: To provide a radio interference canceller device for eliminating effect of a radio interference independently of the direction of the radio wave. SOLUTION: The canceller device is equipped with a main antenna 4 having the same polarization characteristic as that possessed by a radar transmission radio wave 6, an auxiliary antenna 8 having a crossing polarization characteristic orthogonal to the polarization characteristic of the main antenna 4, and a jamming wave elimination circuit 14 for obtaining an objective signal 17 with the effect of the radio interference 9 eliminated therefrom by removing a radio wave received by the auxiliary antenna 8 from a radio wave received by the main antenna 4. In this event, the effect of the radio interference 9 can be eliminated without deteriorating a radio wave with respect to a detection object 2 regardless of the direction of the radio interference 9 since only a crossing polarization component from a jamming device 3 is received by the auxiliary antenna 8.
