摘要： A FMCW-type radar device generates snapshot data from a beat signal that represents a received condition of the radar device every modulation period. Auto-correlation matrices generated by the snapshot data every modulation period are averaged every set of plural periods. The radar device calculates the target azimuth of a target object such as a preceding vehicle based on the averaged auto-correlation matrix based on MUSIC (MUltiple SIgnal Classification) method. This averaging is performed by weighting average based on an amount of mixed noise (or an interference amount) contained in the snapshot data in each modulation period. A weighting coefficient to be applied to the auto-correlation matrix in each modulation period is set to a value corresponding to the amount of mixed noise, namely, the interference amount of this modulation period. The weighting coefficient becomes large when the interference amount is small, and on the other hand, becomes small when it is large.
摘要翻译： FMCW型雷达装置从表示每个调制周期的雷达装置的接收状态的拍子信号产生快照数据。 每个调制周期由快照数据生成的自相关矩阵在多个周期的集合中取平均值。 雷达装置基于基于MUSIC（多尺度分类）方法的平均自相关矩阵来计算诸如前一车辆的目标对象的目标方位角。 该平均化是通过基于每个调制周期中包含在快照数据中的混合噪声量（或干扰量）的加权平均来执行的。 将在每个调制周期中应用于自相关矩阵的加权系数设置为与混合噪声量即该调制周期的干扰量相对应的值。 当干扰量小时，加权系数变大，另一方面，当它大时变小。
