Radar apparatus of a vehicle for accurately detecting a target having a path in a lane of the vehicle
First Claim
1. A radar apparatus of a vehicle, comprising:
- a radar unit for detecting a position of a target based on a reflection beam reflected from the target and for outputting data related to the detected position;
scanning control means for controlling a direction of a beam radiation axis of the radar unit to the target;
certainty-factor determining means for determining a certainty factor of the target based on data presently detected by the radar unit and data previously detected by the radar unit;
certainty-factor adjusting means for controlling the certainty factor such that a changing rate to the certainty factor is determined based on the data from the radar unit, the certainty factor being adjusted by the changing rate; and
first changing-rate varying means for varying the changing rate to one of a plurality of predetermined values based on a target center positional angle to the target, whereby said certainty-factor adjusting means adjusts the certainty factor by said changing rate.

Abstract
A radar apparatus includes a radar unit which detects a position of a target based on a reflection beam reflected from the target and outputs data related to the detected position. A scanning control unit controls a direction of a beam radiation axis of the radar unit to the target. A certainty-factor determining unit determines a certainty factor of the target based on data presently detected by the radar unit and data previously detected by the radar unit. A certainty-factor adjusting unit controls the certainty factor such that a changing rate to the certainty factor is determined based on the data from the radar unit, the certainty factor being adjusted by the changing rate. A first changing-rate varying unit varies the changing rate to one of a plurality of predetermined values based on a target center positional angle to the target, whereby the certainty-factor adjusting unit adjusts the certainty factor by the changing rate.
