1. being used for the radar sensor of automobile, there is multiple transmittings and receiving antenna (10,10'"'"'), side of the these antenna at themIt is different on the directional characteristic of parallactic angle and their each assigned mixers (12,12'"'"'), the mixer will emit signal(S) it is mixed with received signal (E), wherein at least one of mixer (12) is transmission mixer, and in mixerAt least another (12'"'"') have lesser transimission power,It is characterized in that,Relative to being different in its transimission power mixer (12,12'"'"'), transmitting and the distribution of receiving antenna (10,10'"'"') are closedIt is asymmetrical in optical axis (28), wherein the radar sensor has transmitting and the receiving antenna (10,10'"'"') of even number,And it is used as in optical axis for the mixer (12) of the transmitting of half quantity and receiving antenna (10) by as transmission mixer(28) antenna configuration with strong transmission power on side, and the transmitting for being used for the other half quantity and receiving antenna are (10'"'"')Mixer (12'"'"'), i.e., as isolation mixer, as with weak transmission power or not having on the other side of optical axis (28)(10'"'"') the antenna of any transmission power configures and has than the lesser transmission of antenna by as transmission mixer configurationPower, wherein the left and right side in vehicle front bumper region respectively installs a radar sensor, and two radar sensingsDevice is mutually mirror configuration, so that their localization field is also to be mutually mirror.
