    • The radar apparatus includes a transmit/receive section having a function of emitting a transmission wave, receiving the transmission wave reflected from a reflecting object, and outputting a reception signal having a signal level depending on the intensity of the received transmission wave, a control section controlling the transmit/receive section to transmit the transmission wave a predetermined number of times in the same direction, an integrating section successively integrating the reception signal successively outputted from the transmit/receive section to thereby successively form an integrated signal while the transmit/receive section repeatedly emits the transmission wave in the same direction, and a detector section judging whether or not the integrated signal enables detection of the reflecting object.

    • A radar apparatus for a vehicle radiates laser beams and integrates a plurality of received signals corresponding to the same plurality of successively radiated laser beams. Thus, the sensitivity to detect a beam-reflecting body is improved. Further, a sampling start timing of the received signals is delayed as a delay time relative to a radiation timing of the laser beam corresponding to the received signal. By changing the delay time, beam-reflecting bodies throughout all detection distances can be detected even when the number of sampling points is made smaller than the number of sampling points required to cover all the detection distances in order to reduce the integration processing load.
    • 用于车辆的雷达装置辐射激光束并对与相同的多个相继辐射的激光束相对应的多个接收信号进行积分。 因此,提高了检测光束反射体的灵敏度。 此外,接收信号的采样开始定时相对于对应于接收信号的激光束的辐射定时延迟为延迟时间。 通过改变延迟时间,即使使采样点的数量小于覆盖所有检测距离所需的采样点的数量以减少积分处理负荷,也可以检测所有检测距离内的光束反射体。
