摘要： According to a conventional method of correlating beat frequencies in a radar device, a detecting state of a target differs at the time of up-chirping and at that of down-chirping, so that, when the number of peaks of beat frequencies does not match with each other, there occurs a situation in which the beat frequencies cannot be accurately correlated.The radar device herein provided includes a transmission unit for transmitting a frequency-modulated continuous wave (FMCW) signal; a reception unit for generating a beat signal from the transmission signal and a reception signal corresponding thereto; a beat-frequency generating unit for obtaining a beat-frequency distribution corresponding to the beat signal; an up-chirp beat-frequency tracking means and a down-chirp beat-frequency tracking means for performing tracking processing on a beat signal; and an up-chirp target-detection means and a down-chirp target-detection means for calculating a range and range-change rate to a target based on a beat signal's frequency distribution.

摘要： A perpendicular magnetic recording head includes a main magnetic pole layer and an auxiliary yoke layer that overlaps the main magnetic pole layer as viewed in a top view and is magnetically coupled to the main magnetic pole layer. The main magnetic pole layer includes a pole straight part exposed to an opposing surface opposite a recording medium, and a flared part that extends from the pole straight part in a height direction, the flared part broadening in a track width direction as the flared part extends in the height direction. The auxiliary yoke layer includes a flared part that extends from the recording medium-opposing surface, the flared part broadening in the track width direction as the flared part extends in the height direction. The flared part of the auxiliary yoke layer is disposed at a position located closer to the rear side in the height direction than the flared part of the main magnetic pole layer. The flared part of the main magnetic pole layer is formed at a flare angle greater than a flare angle of the auxiliary yoke layer.
