Interference detection apparatus, interference canceller, radar apparatus, interference detection method, and interference detection program

摘要

An interference rejection device includes a change amount calculator, a detector, and a rejecter. The change amount calculator is configured to find change amounts in at least one of amplitude and phase of received signals of a plurality of sweeps in a distance direction between a first distance and a second distance. The detector is configured to detect radar interference occurring between the first distance and the second distance by comparing the change amounts calculated by the change amount calculator between the plurality of sweeps. The rejecter is configured to reduce the amplitude of the received signal corresponding to a position of the radar interference.
