A radar reception device is provided. The device includes a reception signal acquirer, a signal processor, a PPI-scope generator, an A-scope generator, a display output unit, and a user interface. The reception signal acquirer acquires, in an Rθ-coordinate system, a reception signal received by an antenna that rotates at a predetermined cycle. The signal processor performs signal processing on the reception signal in the Rθ-coordinate system according to a distance, and outputs the processed signal in the Rθ-coordinate system. The PPI-scope generator converts the processed signal from the Rθ-coordinate system into an XY-orthogonal coordinate system and generates a radar image in a PPI-scope. The A-scope generator generates a radar image where the reception signal before being signal-processed is illustrated in an A-scope. The display output unit displays the PPI-scope radar image and the A-scope radar image on a display unit simultaneously. The user interface accepts a user input. |
