Radar device

摘要

A radar device (10) comprising a transmission antenna (14) for transmitting electromagnetic waves; a reception antenna (15) for receiving waves; and a detector unit (34) which detects, based on the reflected waves, the positions of a preceding vehicle and a preceding object, judges the preceding object to be the same as the preceding vehicle if the position of the preceding object is in a predetermined preceding vehicle judging range with the position of the preceding vehicle as a reference, detects the positions of an oncoming vehicle and an oncoming object and judges the oncoming object to be the same as the oncoming vehicle if the position of the oncoming object is in a predetermined oncoming vehicle judging range with the position of the oncoming vehicle as a reference; wherein the oncoming vehicle judging range is set to be narrower than the preceding vehicle judging range.

主权项

1. A radar device mountable on a present vehicle, the radar device comprising:
a transmission antenna configured to transmit electromagnetic waves to an object; a reception antenna configured to receive waves reflected by said object; a detector configured to detect, based on said reflected waves:
positions of a preceding vehicle and a preceding object traveling in the same direction as the present vehicle, andpositions of an oncoming vehicle and an oncoming object traveling in a direction opposite to the direction in which said present vehicle is traveling; and a position comparator configured to:
judge said preceding object to be the same as said preceding vehicle if the position of said preceding object is in a predetermined preceding vehicle judging range that is determined using the position of said preceding vehicle as a reference, andjudge said oncoming object to be the same as said oncoming vehicle if the position of said oncoming object is in a predetermined oncoming vehicle judging range that is determined using the position of said oncoming vehicle as a reference, wherein said oncoming vehicle judging range is set to be narrower than said preceding vehicle judging range so as not to incorrectly recognize said oncoming object as said oncoming vehicle.
