Abstract
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.
