1. A radar device comprising:
- a processor configured to function as;
a detecting unit configured to detect a lateral location of a target relative to a vehicle equipped with the radar device, on the basis of reflected waves from the target;
a selecting unit configured to select a predetermined number of detection values, the predetermined number depending on a turning radius of the vehicle, from a detection value history including detection values of the lateral location detected by the detecting unit in chronological order; and
a determining unit configured to determine a definite value of the lateral location on the basis of a calculation of the detection values selected by the selecting unit,wherein the selecting unit decreases the predetermined number of the detection values as the turning radius decreases.

Abstract
There is provided a radar device. A detecting unit is configured to detect a lateral location of a target relative to a vehicle equipped with the radar device, on the basis of reflected waves from the target. A selecting unit is configured to select a predetermined number of detection values from a detection value history including detection values of the lateral location detected by the detecting unit in chronological order. The predetermined number depends on a turning radius of the vehicle. A determining unit is configured to determine a definite value of the lateral location on the basis of the detection values selected by the selecting unit.

4. A signal processing method comprising:
-
a detecting process of detecting a lateral location of a target relative to a vehicle equipped with a radar device, on the basis of reflected waves from the target; a selecting process of selecting a predetermined number of detection values, the predetermined number depending on a turning radius of the vehicle, from a detection value history including detection values of the lateral location detected by the detecting process in chronological order; and a determining process of determining a definite value of the lateral location on the basis of a calculation of the detection values selected by the selecting process, wherein the selecting process decreases the predetermined number of the detection values as the turning radius decreases.
