    • PROBLEM TO BE SOLVED: To provide a technique that accurately determines whether or not information on a target is information on a ghost actually not existing.SOLUTION: The radar device determines whether or not a specific peak signal exists in a distant frequency by a frequency equivalent to a frequency of one peak signal selected in a plurality of peak signals from a frequency of a peak signal existing in a first frequency, and when the peak signal exists, excludes target information corresponding to the selected peak signal from an output object of the radar device. Accordingly, whether or not the selected peak signal is a peak signal of a ghost corresponding to a target actually not existing can be accurately determined, and it is possible to prevent the radar device from outputting the target information that is not originally a control object.

    • PROBLEM TO BE SOLVED: To improve the detection accuracy of a target existing in a near distance.SOLUTION: A rader device includes a generating portion, an estimating portion, and a determining portion. The generating portion generates a frequency spectrum from a beat signal corresponding to a predetermined period. The estimating portion estimates a peak frequency corresponding to a target on the basis of position information of the target corresponding to a past period. The determining portion determines whether the peak frequency is a peak corresponding to the target or not by comparing power near the peak frequency estimated by the estimating portion with a predetermined threshold value, concerning the frequency spectrum corresponding to a latest period.

    • PROBLEM TO BE SOLVED: To prevent decline of detection accuracy of an azimuth angle caused by approximation of each peak frequency of a plurality of target objects. SOLUTION: In this signal processing device of a radar transmitter/receiver for receiving a reflected signal of a transmission signal subjected to frequency modulation as a reception signal by an antenna group, and generating a beat signal having a frequency corresponding to a frequency difference between the transmission signal and the reception signal relative to each antenna, azimuth angle candidates of the target object are detected based on a phase difference of beat signals in a common frequency relative to each pair of antennas, and an azimuth angle candidate agreeing in a prescribed error range with a predicted azimuth angle predicted from a variation of a detected azimuth angle detected in the past from among the azimuth angle candidate group is extracted, and since the azimuth angle of the target object is detected based on the predicted azimuth angle and the extracted azimuth angle candidate, even when detection accuracy of the azimuth angle candidate is lowered by approximation of each peak frequency of the plurality of target objects, accuracy decline of the detected azimuth angle can be prevented by using the predicted azimuth angle.

      SOLUTION: This radar device alternately repeating transmission of a radar signal and pause of transmission has a storage part for storing a plurality of combinations formed respectively, by combining the frequency with a transmission time so that at least either of the frequency of the radar signal and the transmission time, when transmission is performed is different; and a control part for selecting the frequency and the transmission time of the transmitted radar signal from among the plurality of combinations. The control part changes the frequency and the transmission time of the transmitted radar signal from the first combination in the plurality of combinations to the second combination at each prescribed timing, to thereby avoid with high accuracy, duplication of at least either the frequency or the transmission time of each signal from mutual radar devices.
