摘要： A radar device is realized in which an object and extraneous waves such as radar interference or white noise are distinguished and displayed in different display forms. Subtraction Flag Generator 6 determines the time-wise continuity and the planar consecutiveness of target echo data. The time-wise continuity is an amount that indicates the extent to which significant echo data continued to be present at the same position, and is obtained from the echo data of a past predetermined number of sweep rotations. Planar consecutiveness indicates the extent to which significant echo data is present around target echo data, and is obtained by acquiring in a planar fashion echo data for each of predetermined amounts in a distance direction and a heading direction, centered around the target echo data. When Subtraction Flag Generator 6 detects that there is either of time-wise continuity and planar consecutiveness, Subtraction Flag Generator 6 attaches a subtraction flag “1”. Subtraction Processor 9 sets a low attenuation amount for the data level when the subtraction flag is “1”, and sets a fast attenuation amount when the subtraction flag is “0”.
