PROBLEM TO BE SOLVED: To provide a radar device capable of heightening sufficiently target position detection accuracy, even when many radio wave reflectors exist, mutual intervals among a radar device, the target, and the radio wave reflectors are comparatively short, and the target is a moving body having a discontinuous motion. SOLUTION: This device includes a radio wave reflector database for storing the position and the reflection direction of the radio wave reflector as radio wave reflection information, and a target position detection means for detecting the target position on the basis of the arrival direction of a propagating indirect wave formed from the radio wave emitted from the target and reflected by the radio wave reflector, the propagation distance, and a propagation route of the indirect wave calculated from the radio wave reflection information.
