Abstract
A radar device for detecting an object in front of the radar device, has a plurality of antennas, wherein the object is detected based on each reception signal received by two or more of the plurality of antennas, a position specification section for specifying a position of the object by using each reception signal received by the two or more of the plurality of antennas; and an object detection section for confirming an existence of the object if the position specified by the position specification section is in a predetermined range.
Claims6
A radar device for detecting an object in front of the radar device, comprising:
- a plurality of antennas, wherein the object is detected based on reception signals received by the plurality of antennas;
- a position specification means for specifying a position of the object by using the reception signals received by the plurality of antennas;
- a narrow angle transmission means which, when the position specified by the position specification means is in the predetermined range, transmits a second transmission signal with a directivity of a narrower angle than that of a first transmission signal corresponding to the reception signals used in the position specification means, and
- a confirmation means for confirming the existence of the object based on a reflection signal generated by the second transmission signal from the narrow angle transmission means being reflected by the object.
A detection method in a radar device comprising:
- a plurality of antennas, wherein an object in front of the radar device is detected based on reception signals received by the plurality of antennas, the method comprising the steps of:
- specifying a position of the object by using the reception signals received by the plurality of antennas,
- transmitting a second transmission signal with a directivity of a narrower angle than that of a first transmission signal corresponding to the reception signals used in the step of specifying the position of the object when the position specified is in a predetermined range;
- and
- confirming an existence of the object based on a reflection signal generated by the second transmission signal being reflected by the object.
