    • A vehicle perimeter monitor having a high range-finding performance of a short distance and capable of presenting correct information to a driver is provided. A radar 1 including a transmitting antenna 2 and a receiving antenna 3 is fixed on a support member 8 which is a support member integral with a door mirror 7. Accordingly, even if the driver changed viewing direction of the door mirror 7, the positions the transmitting antenna 2 and the receiving antenna 3 relative to the door mirror 7 are kept constant. Therefore, though a part of the radiated transmit wave may be reflected by the door mirror 7, by measuring the reflected wave by the door mirror 7 beforehand, the reflected wave can be canceled by a signal processing circuit part 5.
    • 提供了具有很短距离的高测距性能并且能够向驾驶员呈现正确信息的车辆周边监视器。 包括发射天线2和接收天线3的雷达1固定在作为与门镜7一体的支撑构件的支撑构件8上。因此,即使驾驶员改变了门镜7的观察方向, 发送天线2和接收天线3相对于门镜7保持恒定。 因此,尽管辐射发射波的一部分可能被门镜7反射,但是通过预先通过门镜7测量反射波,可以通过信号处理电路部分5抵消反射波。
