    • In a configuration of a technique in the related art, since two Doppler sensors are used to measure velocity in two directions, and a set of transmission circuit and reception circuit are provided for each of directions to be measured, a device becomes large and expensive. Moreover, in the related art, since signal processing is performed by using output of each of the two Doppler sensors, axis adjustment in each of emission directions of the two Doppler sensors needs to be performed separately, therefore there is a difficulty that appropriate axis adjustment is complicated and difficult. An absolute velocity measuring device is mounted in a vehicle, and includes a transceiver for transmitting and receiving a wave, a transmission-wave branch section that branches a unidirectional wave transmitted from the transceiver in a plurality of directions, and converges reflected waves of waves branched in the plurality of directions from the ground into the unidirectional wave to be received by the transceiver, and a signal processing section that obtains a signal based on a reflected wave that has been received from the transceiver, and processes the obtained signal and thus calculates a plurality of kinds of behavioral information of the vehicle, and then outputs the relevant behavioral information.
    • 在现有技术的结构中,由于使用两个多普勒传感器来测量两个方向上的速度,并且为每个测量方向设置一组发送电路和接收电路,因此设备变大并且昂贵。 此外,在现有技术中,由于通过使用两个多普勒传感器中的每一个的输出来执行信号处理,因此需要分开进行两个多普勒传感器的发射方向的各轴的调整,因此难以适当的轴线调整 是复杂而困难的。 绝对速度测量装置安装在车辆中,并且包括用于发送和接收波的收发器,在多个方向上分支从收发器发送的单向波的发送波分支部分,并且使波分支的波的反射波收敛 在从地面到由收发器接收的单向波的多个方向上,以及信号处理部,其基于从收发器接收到的反射波获得信号,并且处理所获得的信号,从而计算出 车辆的多种行为信息,然后输出相关的行为信息。
