PURPOSE:To achieve higher operability facilitating the determination of a vertical bearing by applying a marker for indicating the position of other moving objects to a three-dimensional coordinate image where a specified moving object is positioned at the origin of a specified three-dimensional coordinate based on relative position information of the individual moving objects to form a three-dimensional radar image, which is displayed. CONSTITUTION:Three-dimensional coordinate information or the like for each of moving objects A-F is housed into a moving object table 10 and the information is updated at each specified time with a table updating section 20. The information updated is read out with a relative position detecting section 30 to detect relative positions of other moving objects with respect to a specified moving object. An image plotting section 40 positions the specified moving object at the origin of a three-dimensional coordinate with an ongoing direction taken on the (y) axis, the horizontal direction on the (x) axis and the vertical direction on the (z) axis based on the information on the relative positions to form a three-dimensional radar image having markers indicating the relative positions of the other moving objects. The image is shown on a display device 91 by an image display section 50. |
