Abstract
According to one embodiment, a dual polarization radar apparatus includes a received power calculation unit configured to calculate a horizontal polarization received power and a vertical polarization received power, the horizontal polarization received power indicating a power value of a horizontal polarization received signal reflected from an observation target, the vertical polarization received power indicating a power value of a vertical polarization received signal reflected from the observation target, a power ratio calculation unit configured to calculate a power ratio between the horizontal polarization received power and the vertical polarization received power, and an interference judgment unit configured to judge that an interference signal is mixed to the horizontal polarization received signal or the vertical polarization received signal when the power ratio is greater than a predetermined threshold value.
