    • An FM-CW radar detects at least one of the relative distance and the relative speed of a predetermined object based on the frequencies of projection portions observed in the frequency spectrums of beat signals in an ascending-modulation section and a descending-modulation section, where the projection portions are generated by one and the same object. The radar determines the moving speed of a predetermined moving object such as a vehicle or the like having the radar mounted thereon, and the frequency difference between the projection portions observed in the frequency spectrums of the beat signals in the ascending-modulation section and the descending-modulation section is inversely calculated, where the frequency difference corresponds to the stationary object, and a predetermined pair corresponding to the frequency difference is extracted on a priority basis.
    • FM-CW雷达基于在上行调制部分和下行调制部分中的拍频信号的频谱中观察到的投影部分的频率来检测预定对象的相对距离和相对速度中的至少一个,其中 突出部分由同一个物体产生。 雷达确定安装有雷达的车辆等预定移动物体的移动速度,以及上升调制部中的拍频信号的频谱中观察到的投射部之间的频率差, 调制部分被反算,其中频差对应于静止对象,并且基于优先级提取对应于频差的预定对。

    • A radar device precisely detects a target in short time intervals by detecting a true peak frequency with high accuracy via a calculation which does not require a large amount of computation. A discrete frequency spectrum of a beat signal multiplied by a window function is determined, and values of signal strength at two discrete frequencies which are, respectively, higher and lower than a peak frequency of the discrete frequency spectrum of the beat signal and which are adjacent to the peak frequency. The frequency difference between the discrete peak frequency of the beat signal and the peak frequency of the window function is then determined from the ratio between the values of signal strength at those two discrete frequencies adjacent to the peak frequency. Thus, the true peak frequency of the beat signal is determined with a high frequency resolution.
    • 雷达装置通过不需要大量计算的计算,以高精度检测真正的峰值频率,以短时间间隔精确地检测目标。 确定乘以窗口函数的拍频信号的离散频谱,以及两个离散频率处的信号强度值,分别高于和低于拍频信号的离散频谱的峰值频率并且相邻的频率 到峰值频率。 然后,从与峰值频率相邻的那两个离散频率处的信号强度的值之间的比率确定差拍信号的离散峰值频率与窗口函数的峰值频率之间的频率差。 因此,以高频分辨率确定拍频信号的真峰值频率。
