1. A radar device which receives reflected waves from objects, and derives still targets, comprising:
- a determining unit that determines whether any other still target exists at a position within a predetermined distance of a reference target which is a still target existing at a position closest to a position of a vehicle in a longitudinal direction; and
a setting unit that enhances a reliability to determine the reference target as a roadblock, in a case where the number of other still targets existing at positions within the predetermined distance of the reference target is equal to or less than a predetermined value.

Abstract
A radar device which receives reflected waves from objects, and derives still targets, includes: a determining unit that determines whether any other still target exists at a position in the vicinity of a reference target which is a still target existing at a position closest to a position of a vehicle in a longitudinal direction; and a setting unit that makes it easy to determine the reference target as a roadblock, in a case where the number of other still targets existing at positions in the vicinity of the reference target is equal to or less than a predetermined value.

7. A radar device which receives reflected waves from objects, and derives still targets, and outputs target data items related to the still targets to a data using device which uses the target data items, comprising:
-
a determining unit that determines whether any other still target exists at a position within a predetermined distance of a reference target which is a still target existing at a position closest to a position of a vehicle in a longitudinal direction; and an easing unit for reducing conditions that reduces an output condition for outputting a target data item related to the reference target to the data using device, in a case where the number of other still targets existing at positions within the predetermined distance of the reference target is equal to or less than a predetermined value. - View Dependent Claims (8)

9. A signal processing method of a radar device which receives reflected waves from objects, and derives still targets, comprising:
-
determining whether any other still target exists at a position within a predetermined distance of a reference target which is a still target existing at a position closest to a position of a vehicle in a longitudinal direction; and enhancing a reliability to determine the reference target as a roadblock, in a case where the number of other still targets existing at positions within the predetermined distance of the reference target is equal to or less than a predetermined value.
