Claims

[Scope of utility model registration request]

Radar video signal to PPI (Plane Po5
A radar information processing device for displaying information on an intermediate frequency signal (indicator) includes first and second intermediate frequency amplifiers to which a received signal converted into an intermediate frequency signal is commonly input; first and second phase detectors connected to the first and second intermediate frequency amplifiers, respectively; first and second phase detectors connected to the first and second intermediate frequency amplifiers, respectively; and the first and second phase detectors connected to the first and second intermediate frequency amplifiers, respectively; first and second cancelers each connected to a wave detector; a first switch for switching the outputs of the first wave detector and the first canceller; and a first switch for switching the outputs of the second wave detector and the second canceler; a second switch; a storage unit that stores outputs obtained by dividing the output of the first switch into distance directions and azimuth directions; and output data stored in the storage unit that is continuous in the azimuth direction and exists at a value greater than or equal to a certain value. and a gain controller that reduces the gain of the second intermediate frequency amplification amplifier only during that time when the second intermediate frequency amplification occurs.
