PROBLEM TO BE SOLVED: To provide a target data acquisition method capable of detecting the position/speed of a target in a short time without enlargement.SOLUTION: A rader device includes a mode control unit 9 for outputting a CW (continuous wave) mode when target detection information indicates no target detection and a mode command instructing an FMCW mode when the target detection information indicates a target detection, a transmission signal generation unit 3 for generating a transmission signal, a transmission/reception unit 4 for receiving a reflection wave to output it as a reception signal, a reception signal processing unit 5, a CW target detection unit 6 for outputting the target detection information under the condition of detecting spectrum waveform data larger than a threshold in the case of the CW mode and obtaining and outputting azimuth angle information and a CW speed at this time, an FM target detection unit 6 for obtaining the speed of the target as an FM speed from the spectrum waveform data in the case of the FMCW mode and its distance to output them, and a target matching determination unit 8 for outputting the speed, the azimuth angle information and the distance when the CW speed and the FM speed match each other. |
